Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich Jan 1994

Predicting The Past, Recounting The Future: Human Ecology And A Prehistory Of Consciousness, Paul Faulstich

Pitzer Faculty Publications and Research

This paper is concerned with the organic derivation and primary meaning of Pleistocene finger flutings; I propose that in order to gain insight into the significance of the flutings, we must attempt an understanding of the physical and mental contexts in which they emerged. I suggest that finger flutings provided a cultural record in the Pleistocene which documented thought and action, and made it ready for reflection. Through the process of finger fluting, the human 'self' was objected and reality was modified in the experience of self-consciuosness. I argue that finger flutings, like language, were employed to discover and convey …


An Economic Valuation Of The Jandakot Wetlands, Paul Gerrans Jan 1994

An Economic Valuation Of The Jandakot Wetlands, Paul Gerrans

Research outputs pre 2011

Economists implore the efficient allocation of resources. Paradoxically, where the issue of efficiency has become critically important in recent times, namely the allocation of the environment and its resources and amenity, the techniques of economists have been found wanting and less than fully developed. This paper seeks to address this apparent paradox and deficiency.

This paper provides an economic valuation of the Jandakot wetlands, located to the south of Perth. A referendum style contingent valuation method survey is used to estimate economic value attributable to the preservation of wetlands dependant on the groundwater resource. Event history analysis is explored and …

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin Jan 1993

G93-1191 Glossary Of Water-Related Terms, William L. Kranz, Delynn Hay, James W. Goeke, David Gosselin

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide is a glossary of water quantity, quality and human health related terms involving water. Terms are defined in contexts that could affect Nebraskans. We depend upon water for our very existence. The impact of water quality and quantity issues has never been greater. Yet the terminology used to describe the water we drink, the water we provide to plants and animals, the water stored underground, in lakes, rivers, and oceans, is not well understood by many Nebraskans. This listing of water-related terms is intended to reduce the potential for misunderstanding presentations made by elected officials, environmental agencies and …


Use Of High-Energy Radiation For Degradation Of Environmental Pollutants, Robert D. Guthrie, Manjiri Patwardhan Oct 1992

Use Of High-Energy Radiation For Degradation Of Environmental Pollutants, Robert D. Guthrie, Manjiri Patwardhan

KWRRI Research Reports

The purpose of this project was to explore the advantages and/or limitations of high-energy radiation treatment as a method for degrading organic pollutants, particularly aryl halides, in an aqueous medium. We have done analyses of 60Co-irradiated samples and kinetic studies using pulsed electron beams. For aryl halides containing no more than two fused rings, the main products detected are those of simple halogen replacement by hydrogen, although the amount of aryl halide destroyed was always greater than the total amount of products detected. To accomplish halogen replacement by H, the reaction solvent may not be pure water but must …


Mechanical Backup Systems For Electronic Environmental Controllers, Richard S. Gates, Douglas G. Overhults, Larry W. Turner Jul 1992

Mechanical Backup Systems For Electronic Environmental Controllers, Richard S. Gates, Douglas G. Overhults, Larry W. Turner

Biosystems and Agricultural Engineering Faculty Publications

A series of mechanical backup systems for electronic environmental controllers is presented for a typical finishing swine barn and a typical tunnel ventilated broiler house. The systems consist of mechanical thermostats and timers used in parallel with the electronic controller, designed to ensure animal survival in the event of controller or related hardware failure. For swine housing, three distinct mechanical backup functions are identified; for broiler housing, four distinct mechanical backup functions are identified. Schematic diagrams of the mechanical backup functions are provided and their implementation is described.


A Survey Of Electronic Environmental Controllers, Richard S. Gates, Douglas G. Overhults, Larry W. Turner May 1992

A Survey Of Electronic Environmental Controllers, Richard S. Gates, Douglas G. Overhults, Larry W. Turner

Biosystems and Agricultural Engineering Faculty Publications

Sixteen commercially available electronic environmental controllers were evaluated. The units were classified according to enclosure type, analog versus microprocessor based control, power supply, sensors, alarms, control relays and triac output, interval timers, outside temperature feedback, and retail price. An assessment of these controllers indicated several critical limitations in the application of this technology.

The use of integrated controllers for animal production has the potential for substantial improvements in production efficiencies. If the limitations observed in the present controller technology, as represented by this sample, are addressed, industry acceptance of the technology can be accelerated. A uniform standard to address this …

Identifying Chemical Hazards For Regulation: The Scientific Basis And Regulatory Scope Of California's Proposition 65 List Of Carcinogens And Reproductive Toxicants, William S. Pease

RISK: Health, Safety & Environment (1990-2002)

Noting that the Proposition 65 list has become an authoritative source for hazard identification, Dr. Pease examines its legislative, regulatory and scientific origins. After analyzing the California approach, he offers suggestions for better selection of future regulatory targets.

Water Quality In The Kentucky River Basin, Daniel I. Carey Jan 1992

Water Quality In The Kentucky River Basin, Daniel I. Carey

Information Circular--KGS

Data gathered up to 1990 suggest that water pollution problems existed throughout the Kentucky River Basin. Fecal coliform bacteria in streams was a widespread problem because of the inadequate treatment of municipal wastes, failing septic systems, and agricultural runoff. Iron, lead, manganese, mercury, and silver exceeded State standards and Federal guidelines for drinking water and aquatic life at most of the sample sites for a majority of samples. Aquatic life in many smaller streams in the Knobs region was reduced by chloride discharges from oil and gas operations, according to the Kentucky Division of Water. Organic enrichment and high nutrient …

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque Mar 1991

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque

RISK: Health, Safety & Environment (1990-2002)

Dr. Roqu6 recounts her work as a doctoral candidate at Brown in developing standards for the regulation of airborne carcinogens. Based in part on this experience, she argues that care needs be taken lest those who regulate Risk bury key policy decisions within a mass of often irrelevant technical details.

Colby College Watershed Study: Other Area Studies

In May of 1990, Tilcon-Maine, Inc. submitted an application to mine gravel on the east side of Horse Point Road on Horse Point in the Town of Belgrade. The project site covers 46 acres and the proposed excavation covers 16 acres. An estimated 740,000 cubic yards of material will be removed over a period of six or seven years (Pfister, pers. comm.). According to Tilcon (Timson et al., 1990) the maximum depth of the pit will be 78 feet and the bottom of the pit will be a minimum of 6 feet above the water table. At the present time …

Wildlife Damage Management (Wdm) In The Southern Utah Adc District, United States Department Of Agriculture, Animal And Plant Health Inspection Service, Animal Damage Control

All U.S. Government Documents (Utah Regional Depository)

Across the United States, wildlife habitat has been substantially changed as human populations expand and land is used for human needs. These human uses and needs often compete with wildlife which increases the potential for conflicting human/wildlife interactions. In addition, segments of the public strive for protection for all wildlife; this protection can create localized conflicts between human and wildlife activities.
