Electricity deregulation and the valuation of visibility loss in wilderness areas: A research note.

Visibility in most wilderness areas in the northeastern United States has declined substantially since the 1970s. As noted by Hill et al. (2000), despite the 1977 Clean Air Act and subsequent amendments, human induced smog conditions are becoming increasingly worse. Average visibility in class I airsheds, such as the Great Gulf Wilderness in New Hampshire’s White Mountains, is now about one-third of natural conditions. A particular concern is that deregulation of electricity production could result in further degradation because consumers may switch to lower cost fossil fuel generation (Harper 2000). To the extent that this system reduces electricity costs, it may also affect firm location decisions (Halstead and Deller 1997). Yet, little is known about the extent to which consumers are likely to make tradeoffs between electric bills and reduced visibility in nearby wilderness areas. This applied research uses a contingent valuation approach in an empirical case study of consumers’ tradeoffs between cheaper electric bills and reduced visibility in New Hampshire’s White Mountains. We also examine some of the problems associated with uncertainty with this type of analysis; that is, how confident respondents are in their answers to the valuation questions. Finally, policy implications of decreased visibility due to electricity deregulation are discussed

TINKERING WITH VALUATION ESTIMATES: IS THERE A FUTURE FOR WILLINGNESS TO ACCEPT MEASURES?

This paper examines various methods proposed in the literature to calibrate welfare measures, especially willingness to accept and willingness to pay, derived from contingent valuation surveys. Through simulation and a case study, we hope to provide guidance for empirical welfare measurement in response to the theoretical dispute regarding WTA/WTP disparities.Resource /Energy Economics and Policy,

Crommet Creek Conservation Area Management Plan

The Crommet Creek Conservation Area comprises the largest block of natural lands in the immediate Great Bay watershed, and in New Hampshire’s North Atlantic Coast Ecoregion. It includes the entire watershed of two tidal creeks that flow directly into the Great Bay Estuary. The area has been identified by the Great Bay Resource Protection Partnership as a protection priority due to the size of the natural area; the diversity of habitats and wildlife it supports; and it’s integral role in protecting the regional water quality and resources within the Great Bay Estuary. The Conservation Area includes headwater wetlands, and the entire spectrum of freshwater and estuarine wetland and aquatic communities along both Lubberland and Crommet creeks. The Great Bay is a shallow inland tidal estuary of national importance for migratory birds. The Great Bay supports 29 species of waterfowl, 27 species of shorebirds, 13 species of wading birds, osprey and bald eagle. The Estuary is unique in that it is recessed 9 miles from the ocean along the Piscataqua River. Although development is increasing in the watershed, it remains one of the more healthy and viable estuarine ecosystems on the North Atlantic coast

Trypanosomes are monophyletic: evidence from genes for glyceraldehyde phosphate dehydrogenase and small subunit ribosomal RNA.

The genomes of Trypanosoma brucei, Trypanosoma cruzi and Leishmania major have been sequenced, but the phylogenetic relationships of these three protozoa remain uncertain. We have constructed trypanosomatid phylogenies based on genes for glycosomal glyceraldehyde phosphate dehydrogenase (gGAPDH) and small subunit ribosomal RNA (SSU rRNA). Trees based on gGAPDH nucleotide and amino acid sequences (51 taxa) robustly support monophyly of genus Trypanosoma, which is revealed to be a relatively late-evolving lineage of the family Trypanosomatidae. Other trypanosomatids, including genus Leishmania, branch paraphyletically at the base of the trypanosome clade. On the other hand, analysis of the SSU rRNA gene data produced equivocal results, as trees either robustly support or reject monophyly depending on the range of taxa included in the alignment. We conclude that the SSU rRNA gene is not a reliable marker for inferring deep level trypanosome phylogeny. The gGAPDH results support the hypothesis that trypanosomes evolved from an ancestral insect parasite, which adapted to a vertebrate/insect transmission cycle. This implies that the switch from terrestrial insect to aquatic leech vectors for fish and some amphibian trypanosomes was secondary. We conclude that the three sequenced pathogens, T. brucei, T. cruzi and L. major, are only distantly related and have distinct evolutionary histories

Visual stimulus disrupts the spatial localization of a tactile sensation in Virtual Reality

Phantom limb pain is a neuropathic condition in which a person feels pain in a limb that is not present. Cognitive treatments that visually recreate the limb in an attempt to create a cross modal interaction between vision, and touch/proprioception have shown to be effective at alleviating this pain. With improvements in technology, Virtual Mirror Therapy is starting to gain favor, however, there are currently no applications that utilize passive touch in the same way non-virtual reality applications do. This paper investigates whether a visual stimulus can relocate a tactile stimulus to a different location using principles from the rubber hand illusion and mirror therapy. We demonstrate that a displaced visual stimulus in virtual reality can disrupt accurate spatial perception of a physical vibrotactile sensation however the effects are small and require further investigation

Model Demonstration Elementary Classrooms in Northeast Iowa: The Luther College Project

Luther College has a tradition of elementary teacher preparation stretching back to the tum of the century. It was therefore fitting that Luther College receive the only Eisenhower model demonstration program grant given to an Iowa four-year college. Built on outreaches and contacts developed by a teacher enhancement summer workshop held on the Luther Campus in 1993, the new program extends its outreach to the entire Northeast Iowa region

Adding Fizz to Your Science Classroom

Have you found that your science classes just skip from unit to unit? Do you want to get away from science lessons that stress vocabulary and memorization of facts? Are you pondering how to get your students more involved in science? These were some of the questions we thought about when we designed hands-on experiences in science for upper elementary students. According to the National Research Council in Fulfilling the Promise, Biology Education in the Nation\u27s Schools, future curriculum goals for both elementary and secondary science teaching will emphasize hands-on exploration by the students, the development of skills in observation, comparison, measurement, questioning and understanding and the view of science education as a continuous, interrelated process rather than isolated units of study
