Tb184: Least-Cost Options For The Collection, Treatment, And Disposal Of Biomedical Waste In Maine., Andrew C. Files, Thomas G. Allen, George K. Criner Nov 2002

Tb184: Least-Cost Options For The Collection, Treatment, And Disposal Of Biomedical Waste In Maine., Andrew C. Files, Thomas G. Allen, George K. Criner

Technical Bulletins

This study examines the cost effectiveness of using current treatment technologies to sanitize, disinfect, shred, and dispose of biomedical waste within the state in relation to the costs of current disposal practices in Maine. The study employs a linear programming model to determine the combination of treatment facilities, transportation options, and disposal sites to treat all waste produced in Maine at the lowest statewide cost. A least-cost solution is developed for three different scenarios. The first two scenarios assume that all treated waste must be shredded in accordance with current regulatory requirements. The third scenario assumes that regulations are changed …


Tb185: Designing A Labeling Policy For Genetically Modified Food: Results Of Focus Group Research, Mario F. Teisl, Lynn Halverson, Kelly O'Brien, Brian Roe Oct 2002

Tb185: Designing A Labeling Policy For Genetically Modified Food: Results Of Focus Group Research, Mario F. Teisl, Lynn Halverson, Kelly O'Brien, Brian Roe

Technical Bulletins

The labeling of genetically modified foods is a topic of growing, and sometimes cantankerous, public debate—a debate whose outcome could dramatically alter the operation of the U.S. production agriculture, processing, distribution and retailing sectors. The debate surrounding the labeling of genetically modified foods is largely about how much information to supply to consumers to facilitate effective choice and how that information should be supplied. Although there seems to be empirical evidence of a mainstream desire for the labeling of genetically modified foods, we know of no study that has provided guidance to policy makers as to the best method of …


Tb182: Agricultural Land Changes In Maine: A Compilation And Brief Analysis Of Census Of Agriculture Data, 1850-1997, Soeun Ahn, William B. Krohn, Andrew J. Plantinga, Timothy J. Dalton Mar 2002

Tb182: Agricultural Land Changes In Maine: A Compilation And Brief Analysis Of Census Of Agriculture Data, 1850-1997, Soeun Ahn, William B. Krohn, Andrew J. Plantinga, Timothy J. Dalton

Technical Bulletins

The purpose of this study is to compile the best available long-term historical information on agricultural land use in Maine and to briefly analyze these data to develop a statewide description of Maine's land use history from the mid-1800s to present. Our emphasis is on compiling statistically based information and, in particular, land use data reported in the Census of Agriculture. Objectives were (1) to compile available statewide data on agricultural land and land cover (LULC) in Maine, 1850-1997; (2) to examine temporal and spatial patterns in the LULC of Maine; and (3) to discuss the implications of the major …


Tb171: Investigations Into The Potential Of Measuring Biodiversity In Maine's Forests With Forest Inventory And Analysis (Fia) Data, Thomas G. Allen, Andrew Plantinga Mar 1999

Tb171: Investigations Into The Potential Of Measuring Biodiversity In Maine's Forests With Forest Inventory And Analysis (Fia) Data, Thomas G. Allen, Andrew Plantinga

Technical Bulletins

We present here the results of our initial effort to use FIA data to assess biodiversity in Maine's forests. Biodiversity is a complex issue and, from the start, it was apparent that the FIA data are inadequate for examining all facets of biodiversity. Nevertheless, the FIA provides the most comprehensive and detailed data on Maine's forests and can be used to measure some indicators of forest biodiversity, in particular those related to tree species and stand characteristics.


Tb168: Time-Series Analysis Of Maine Stumpage Prices, John B. Lindahl, Andrew J. Plantinga Oct 1997

Tb168: Time-Series Analysis Of Maine Stumpage Prices, John B. Lindahl, Andrew J. Plantinga

Technical Bulletins

The authors of this bulletin analyze price series for stumpage in Maine. For each available species and product group (sawlogs, pulpwood), they test for stationarity and fit autoregressive integrated moving average (ARIMA ) models to the data based on preliminary diagnostics. They then perform in-sample and out-of-sample price forecasts. The central objective or this work is to characterize the processes for Maine stumpage prices in order to identify opportunities for using reservation price policies to increase timber and land values. These results are of particular value to nonindustrial timber growers for use in scheduling harvests.


Tb166: Maximum Entropy Estimation Of Land Use Shares And Transitions, Andrew J. Plantinga, Douglas J. Miller Mar 1997

Tb166: Maximum Entropy Estimation Of Land Use Shares And Transitions, Andrew J. Plantinga, Douglas J. Miller

Technical Bulletins

This study presents a methodology for estimating land use shares and transitions. Our approach emphasizes the importance of land quality in determining land use. Land quality is an index of the physical characteristics of land such as soil depth, slope, and water capacity. We develop a procedure for recovering the probability that land of a given quality is put t o a particular use. In addition, we identify the probability that land shifts from one use to another.


Tb161: Forestry Investments And Option Values: Theory And Estimation, Andrew J. Plantinga May 1996

Tb161: Forestry Investments And Option Values: Theory And Estimation, Andrew J. Plantinga

Technical Bulletins

This bulletin considers option values related to a principal problem for forestry investors, the timing of harvests. The purpose is to present a general theory of the rotation problem under uncertainty and irreversibility and provide a methodology for empirically estimating option values. Modifications of the framework for analyzing options values related to other aspects of forestry investments are also discussed.


Tb77: Paths Out Of Poverty: Research In The Northeast, William H. Groff, James W. Longest, Louis A. Ploch Sep 1975

Tb77: Paths Out Of Poverty: Research In The Northeast, William H. Groff, James W. Longest, Louis A. Ploch

Technical Bulletins

This publication presents summaries of poverty research done under the aegis of the U.S. Department of Agriculture and the agricultural experiment stations of eight cooperating land grant universities in the Northeast. The project was designated as Paths Out of Poverty and was identified as NE-68. While there is a general introduction, as well as introductions to the two main sections and a concluding summary, the major focus of the publication is the summaries of the various research projects. The reader is directed to the list of references following the entries of the individual states. In most cases reference is made …
