Analysis of the results of Federal incentives used to stimulate energy production

The research program analyzed the Federal incentives used to stimulate nuclear, hydro, coal, gas, oil, and electricity production in order to supply what was learned to the selection of an incentives strategy to induce new energy production from renewable resources. Following the introductory chapter, Chapter 2 examines the problem of estimating effects from a theoretical perspective. Methods of quantifying and identifying the many interactive effects of government actions are discussed. Chapter 3 presents a generic analysis of the result of Federal incentives. Chapters 4 through 9 deal with incentives to energy forms - nuclear, hydro, coal, oil, gas, and electricity. Chapter 10 summarizes the estimated results of the incentives, which are presented in terms of their quantity and price impacts. The incentive costs per million Btu of induced energy production is also discussed. Chapter 11 discusses the parity issue, that is an equivalence between Federal incentives to renewable resources and to traditional energy resources. Any analysis of incentives for solar needs will profit from an analysis of the costs of solar incentives per million Btu compared with those for traditional energy forms. Chapter 12 concludes the analysis, discussing the history of traditional energy incentives as a guide to solar-energy incentives. 216 references, 38 figures, 91 tables

Analysis of federal incentives used to stimulate energy consumption

The purpose of the analysis is to identify and quantify Federal incentives that have increased the consumption of coal, oil, natural gas, and electricity. The introductory chapter is intended as a device for presenting the policy questions about the incentives that can be used to stimulate desired levels of energy development. In the theoretical chapter federal incentives were identified for the consumption of energy as Federal government actions whose major intent or result is to stimulate energy consumption. The stimulus comes through changing values of variables included in energy demand functions, thereby inducing energy consumers to move along the function in the direction of greater quantity of energy demanded, or through inducing a shift of the function to a position where more energy will be demanded at a given price. The demand variables fall into one of six categories: price of the energy form, price of complements, price of substitutes, preferences, income, and technology. The government can provide such incentives using six different policy instruments: taxation, disbursements, requirements, nontraditional services, traditional services, and market activity. The four major energy forms were examined. Six energy-consuming sectors were examined: residential, commercial, industrial, agricultural, transportation, and public. Two types of analyses of incentive actions are presented in this volume. The generic chapter focused on actions taken in 1978 across all energy forms. The subsequent chapters traced the patterns of incentive actions, energy form by energy form, from the beginning of the 20th century, to the present. The summary chapter includes the results of the previous chapters presented by energy form, incentive type, and user group. Finally, the implications of these results for solar policy are presented in the last chapter. (MCW

Ly49A inhibitory receptors redistribute on natural killer cells during target cell interaction

When T effector cells meet antigen-bearing target cells, there is a specific accumulation of T-cell receptors, co-receptors and structural proteins at the point of cell–cell contact. Ly49 inhibitory receptors bind to murine major histocompatibility complex (MHC) class I molecules and prevent natural killer-(NK) cell cytotoxicity. In this study we have tested whether inhibitory receptors accumulate at the point of cell–cell contact when NK cells encounter target cells bearing MHC class I ligands for those inhibitory receptors. We have used RNK-16 effector cells that express Ly49A receptors and have found that there was a specific accumulation of Ly49A receptors at the point of NK cell–target cell contact when the target cells expressed H-2Dd. We also observed that engagement of Ly49A on NK cells resulted in an altered redistribution of potential triggering receptors CD2 and NKR-P1. These data indicate that inhibitory receptors, like activating receptors, may specifically aggregate at the point of cell–cell contact which may be necessary for them to mediate their full inhibitory effect
