Charges that the "impact statements" used to evaluate environmental conditions often serve political ends and often are not well-planned or scientifically valid. (MLH)

Since the statistical theories of turbulence that have developed over the last twenty or thirty years are too abstract and unreliable to be of much use to chemical engineers, this paper introduces the techniques of single point models and suggests some areas of needed research. (BB)

Research is now being done on the behavior of spiders and their role in ecological systems. (BB)

A behavioral setting termed "free time" was identified in the day room of an institution for the retarded. The behavioral mapping technique was used to record behavior and spatial use within this setting. During treatment patients engaged in active and socially involved behavior. (Author)

Explores the use of Landsat imagery in mapping and updating land use for the purpose of planning. Examines Gulf Coast Mexico as a case study, because modern agricultural techniques used to expand the ranching industry have significantly altered the landscape. (Author/BC)

Discusses air and water pollution problems resulting from sulfur in the environment. (MDR)

Discusses the contamination of drinking water supplies from highway salt applications. The toxicological and epidemiological literature indicates, at present, only that sodium in the diet is a factor in hypertension and general human ill-health. (MR)

Research into the epidemiology of lice indicates that infestation is uncommon in blacks, more common in females than males, significantly higher in low income groups, and transmission is by way of articles of clothing. (JD)

Describes some of the ancient geologic history of the Florida Keys from Key Largo to Key West including the effects of glaciers, sea level rise, reef distribution, spurs and grooves, backstepping and ecological zonation, growth rates and erosion. Predicts future changes in this area. (CW)

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)

The study examined: (1) whether or not there was a positive relationship between environmental attitudes and environmental knowledge, and (2) how any relationship that might exist varied among student sub-groups. The "Environmental Knowledge and Attitude Inventory" was administered to 75 rural, 120 suburban, and 102 inner city high school…

This study formulates an empirically derived model of the cognitive transformation of information from urban geographic fields to map representation. It appears that four variables (subject, touring, environmental, map) all contribute to levels of map performance. (BT)

Criticizes the rapidly escalating expenditures in space exploration and suggests the establishment of a moderate unmanned space program in place of the space shuttle in an effort to allocate enough budget for energy research and pollution control. (CC)
