A HOUSEHOLD PRODUCTION ANALYSIS OF FUELWOOD DEMAND IN RHODE ISLAND
No full textA model analyzing household substitution of fuelwood for other heating fuels is needed to clarify the relationship between energy prices and patterns of forest resource utilization. This paper employs the household production methodology to model fuelwood demand in Rhode Island. Data from a cross-sectional survey of 515 households are employed to test a discrete-choice model of household participation in wood-burning and a four-equation system modeling household production of heat and aesthetic benefits from fuelwood and stove capital. Control of selection bias via inclusion of an appropriate instrument allows analysis of aggregate demands. Some broad policy prescriptions applicable to the Northeast generally are presented.Resource /Energy Economics and Policy,

Giardia duodenalis cysts of genotype a recovered from clams in the Chesapeake Bay subestuary, Rhode River
No full textFilter-feeding molluscan shellfish can concentrate zoonotic and anthroponotic waterborne pathogens. Cysts of Giardia sp. were detected by immunofluorescent antibodies in tissues of the clams Macoma balthica and M. mitchelli from Rhode River, a Chesapeake Bay (Maryland) subestuary. Molecular tests identified the cysts as Giardia duodenalis Genotype A, the most common genotype recovered from humans. Macoma clams are burrowers in mud or sandy- mud substrata and preferentially feed on the surface sediment layer. Waterborne Giardia cysts settle rapidly to the bottom in slow-moving waters and contaminate the sediment. Macoma clams do not have economic value, but can serve as biologic indicators of sediment contamination with Giardia sp. cysts of public health importance. These clams can be used for sanitary assessment of water quality

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

EXAMINING CHANGES IN LAND USE AFTER THE SALE OF DEVELOPMENT RIGHTS ON FARMS IN RHODE ISLAND
No full textPurchasable development rights (PDR) programs are generally considered to provide permanent protection of farmland because development rights are separated from the land in perpetuity. However, the programs do not require that farming activities be maintained in the future. Farming may be discontinued on PDR parcels due to changes in economic conditions or if the parcels are converted to non-farm, rural estates. Such changes may reduce the flow of public goods that citizens seek to obtain by implementing PDR programs. We examine changes in land use on PDR parcels to determine if current activities are consistent with program goals. While changes have occurred in the crops and livestock produced on Rhode Island farms, over time, all of the farms on which development rights were purchased during 1985 through 1999 are currently being farmed by the original owners or by new operators who have either purchased or leased the land.Land Economics/Use,
