Reviews types of geothermal energy sources in the western states, including hot brine systems and dry steam systems. Conversion to electrical energy is a major potential use of geothermal energy, although it creates environmental disruptions such as noise, corrosion, and scaling of equipment. (AV)

Traces the development of the civil engineering code of ethics. Points out that the code does have an enforceable provision that addresses the engineer's responsibility toward the environment. Suggests revisions to the code to accommodate the environmental impacts of civil engineering. (TW)

Several ecological concepts--such as population dynamics, the impact of exotic species, integrated pest management, and predation--can be demonstrated utilizing the Gypsy Moth. Suggested materials and procedure for the lessons are provided. (ERB)

Contemporary theories of organizations are assessed to determine whether their propositions and empirical findings can be directly applied to understand and explain voluntary associations. The inquiry is arranged under five types of characteristics: incentive systems and participant commitment, formal structures, leadership and authority,…

ingency on oil supplies will recur later in the 1980s, confirming the need for careful energy planning. Among the factors to be taken into account are: changes in values that affect how people use energy; centralized solutions versus solutions geared to individual and regional needs; and effective use of conservation.

Suggests that although the explained variance in negro immigration rates is much lower than that for whites, comparisons of the patterns of ecological determinants for the two races show more similarities than differences. (Author)

Among the issues discussed are the following: occupational level and work satisfaction, occupational structure and the environment; ecology and organizational and personnel psychology, and the influence of ecological factors. (Author/AM)
