A HOUSEHOLD PRODUCTION ANALYSIS OF FUELWOOD DEMAND IN RHODE ISLAND

A 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,

Flight evaluation of LORAN-C in the State of Vermont

A flight evaluation of LORAN C as a supplement to existing navigation aids for general aviation aircraft, particularly in mountainous regions of the United States and where VOR coverage is limited was conducted. Flights, initiated in the summer months, extend through four seasons and practically all weather conditions typical of northeastern U.S. operations. Assessment of all the data available indicates that LORAN C signals are suitable as a means of navigation during enroute, terminal and nonprecision approach operations and the performance exceeds the minimum accuracy criteria

How Can They Be Silenced? Why Ohio Must Amend Its Civil Statute of Limitations for Child Sexual Abuse Claims

Ohio should abolish the civil statute of limitations for child sexual abuse (CSA) claims because survivors of CSA generally recover memories and come forward with allegations well past the limitations period; courts in states that have eliminated the civil statute of limitations for CSA claims do not become overwhelmed by hearing these claims several years past the date of the abuse; and the perpetrator’s constitutional rights are not violated by abolishing the statute of limitations

The Effects of Positive and Negative Experiences on Subsequent Behavior and Cognition in Capuchin Monkeys (Cebus Apella)

While it is known that acute and chronic stress can impact cognition, less is known about the immediate impacts of minor frustrations or positive experiences on subsequent behavior and cognition in primates. This study used a novel methodology to engineer both a positive and (slightly) frustrating experience, using the same apparatus, in 15 adult capuchin monkeys. Subjects were presented with a working memory task (DMTS) for 30 minutes after the experimental manipulations (or a control). As predicted, the frustrating task prior to testing resulted in a decrease in performance on the DMTS compared to performance after a positive experience or the control. Contrary to predictions, a positive experience did not facilitate performance to higher levels than the control condition. Manipulations also impacted several behaviors. Although there may be different results in different contexts, these results indicate that even mild negative experiences impact subsequent behavior and cognition in primates

Surprises from Quarkonium Decay into Photons

The perturbative QCD approach to quarkonium decay into a photon and hadrons is reconsidered. It is shown that a consistent treatment within perturbative QCD calls for the introduction of a fragmentation contribution which has been neglected so far. The ensuing phenomenological implications are discussed, and, in particular, the possibility of measuring the gluon fragmentation function of the photon is addressed. *To appear in the proceedings of the workshop QCD94, Montpellier, July '94.Comment: 4 pages + 3 figures, uuencoded postscript, Cambridge preprint Cavendish-HEP-94/0

Maxwell-Chern-Simons Q-balls

We examine the energetics of $Q$-balls in Maxwell-Chern-Simons theory in two space dimensions. Whereas gauged $Q$-balls are unallowed in this dimension in the absence of a Chern-Simons term due to a divergent electromagnetic energy, the addition of a Chern-Simons term introduces a gauge field mass and renders finite the otherwise-divergent electromagnetic energy of the $Q$-ball. Similar to the case of gauged $Q$-balls, Maxwell-Chern-Simons $Q$-balls have a maximal charge. The properties of these solitons are studied as a function of the parameters of the model considered, using a numerical technique known as relaxation. The results are compared to expectations based on qualitative arguments.Comment: 6 pages. Talk given at Theory CANADA 2, Perimeter Institut
