Book Description
The 1977 Clean Air Act legally mandated the prevention of significant deterioration (PSD) of air quality related values (AQRVs) on wilderness lands. Federal land managers are assigned the task of protecting these wilderness values. This report contains guidelines for determining the potential effects of incremental increases in air pollutants on natural resources in wilderness areas of the National Forests of California. These guidelines are based on current information about the effects of ozone, sulfur, and nitrogen on AQRVs. Knowledge-based methods were used to elicit these guidelines from scientists and resource managers in a workshop setting. Linkages were made between air pollutant deposition and level of deterioration of specific features (sensitive receptors) of AQRVs known to be sensitive to pollutants. Terrestrial AQRVs include a wide number of ecosystem types as well as geological and cultural values. Ozone is already high enough to injure conifers in large areas of California and is a major threat to terrestrial AQRVs. Aquatic AQRVs include lakes and streams, mostly in high elevation locations. Current sulfur and nitrogen deposition is probably too low to warrant immediate concern in most areas (with the exception of nitrogen deposition at some locations in southern California), although the low buffer capacity of many aquatic systems in California makes them sensitive to potential future increases in acidity. Visibility is considered as a discrete AQRV. Guidelines are presented for determining degradation of visibility based on sensitive views in wilderness areas. Estimates of current deposition of ozone, sulfur, and nitrogen are compiled for all California wilderness areas. Recommendations are included for resource monitoring, data collection, and decision criteria with respect to the disposition of permit applications.

Book Description
John Sculley In the short history of personal computing, the task of the software programmer has been one of the least recognized-but one of the most significant-in the industry. In addition to defining the prob lems, and presenting the solutions, the software programmer is con fronted with the challenge of having to predict what combination of ideas and technologies will move the industry forward in the most compelling way. Even though we've seen the development of tremendous applications in a surprisingly short period of time, the most difficult problems often surface when we try to elevate a suc cessful local idea to the international arena. In the case of Apple Computer, these challenges become especially profound when you consider that Apple sells Macintosh not just in the United States, but in Japan, China, the Middle East, Africa, East ern Europe, and even to the United Nations itself. Of course, this means that the personal computer must work everywhere around the world. But more significantly, it also means that the software must reflect the uniqueness of a given culture, its language, morals, and even its sense of humor. To step away from a narrowly-defined, nationally-based paradigm for software development, programmers, management, and entire corporations must learn to recognize what elements of an interface, problem solving technique, documentation illustration, package de sign, and advertisement are local, and which elements are appro priate for global markets.

Book Description
Soil and cambium temperatures must be known to ascertain certain effects of prescribed fires on trees. Thermocouple-based systems were devised for measuring soil and cambium temperatures during prescribed fires. The systems, which incorporate both commercially available and custom components, perform three basic functions: data collection, data retrieval, and data translation. Although the systems and procedures for using them were designed for research purposes, they could be adapted for monitoring operational prescribed fires.
