Demand for Wildlife Hunting in British Columbia
We present estimates of the demand for hunting licenses by residents and non residents in British Columbia for the period 1971â2000. We obtain estimates of both short-run and long- run price elasticities and discuss their revenue implications for future fee increases. We find the demand by non residents to be strongly correlated with U.S. income variation over the business cycle, but find no such role for cyclical income variation for resident hunters. The ability of the government to increase revenues from resident hunters turns out to be limited, particularly in the long run, while greater opportunities exist to raise revenues from U.S. hunters as short- and long-run price elasticities of demand are quite inelastic. We argue that conservation surcharges on foreign hunters are one way to capture more of the resource rent.recreation demand, resource revenues and rent capture, conservation surcharges
Demand for Wildlife Hunting in British Columbia
We present estimates of the demand for hunting licenses by residents and non residents in British Columbia for the period 1971â2000. We obtain estimates of both short-run and long-run price elasticities and discuss their revenue implications for future fee increases. We further find the demand by non residents to be strongly correlated with U.S. income variation over the business cycle; however, we find no such role for cyclical income variation for resident hunters. Finally, we demonstrate that hunters respond differently to conservation surcharges on hunting licenses relative to direct licensing charges, which has implications for policy makers introducing environmental surcharges in various contexts.recreation demand, environmental surcharges, resource revenues and rent capture
The Effect of Uncertainty on Contingent Valuation Estimates: A Comparison
We examine the impact of uncertainty on contingent valuation responses using (1) a survey of Canadian landowners about willingness to accept compensation for converting cropland to forestry and (2) a survey of Swedish residents about willingness to pay for forest conservation. Five approaches from the literature for incorporating respondent uncertainty are used and compared to the traditional RUM model with assumed certainty. The results indicate that incorporating uncertainty has the potential to increase fit, but could introduce additional variance. While some methods for uncertainty are an improvement over traditional approaches, we caution against systematic judgments about the effect of uncertainty on contingent valuation responses.respondent uncertainty, willingness to accept, contingent valuation
Divergence between WTA and WTP Revisited: Livestock Grazing on Public Range
The research reported here provides further empirical support for the contention that there is a divergence between WTA and WTP. The conclusion is based on results from a 2002 survey of Nevada ranchers that asked about willingness to pay for public forage and WTA compensation to part with grazing rights. WTP and WTA are estimated simultaneously, with the estimators used to demonstrate a statistically significant divergence between WTP and WTA. The simultaneous estimation allows us to identify ranch characteristics that influence the discrepancy in valuations. Ranch size, public grazing allotment, financial distress, and long term commitment to ranching are all significant influences on the disparity. We interpret these results both with respect to general differences in welfare measures and with respect to ranch policy.contingent valuation methods, dichotomous choice surveys, WTA versus WTP, grazing rights and public forage
Are Agricultural Values a Reliable Guide in Determining Landownersâ Decisions to Create Carbon Forest Sinks?
This research examines the effects of various factors on farmer participation in agricultural tree plantations for economic, environmental, social and carbon-uptake purposes, and potential costs of sequestering carbon through afforestation in western Canada. Using data from a survey of landowners, a discrete choice random utility model is used to determine the probability of landownersâ participation and corresponding mean willingness to accept (WTA) compensation for a tree-planting program. WTA includes positive and negative benefits to landowners from planting trees, benefits not captured by foregone returns from agricultural activities on marginal land. Estimates of WTA are less than foregone returns, but even so average costs of creating carbon credits still exceed their projected value under a CO2-emissions trading scheme.Willingness to accept compensation for tree planting, afforestation, climate change

Pembentukan Undak Batugamping dan Hubungannya dengan Struktur Diapir di Perairan Tanjung Awar-awar Paciran Jawa Timur
Batuan yang mendominasi di daerah penyelidikan adalah batugamping koral Formasi Paciran zona Rembang. Batugamping koral inilah membentuk undak pantai di Tanjung Awar-awar dan di pantai Tuban dan sekitarnya. Terdapatnya undak batugamping ini, menandakan adanya pengangkatan secara vertikal pada satuan batuan ini.
Batimetri daerah penyelidikan secara umum merupakan dataran dimana bagian yang dangkal terdapat di bagian baratdaya (ke arah pantai) dengan kedalaman 2 meter dan terdalam ke arah timurlaut dengan kedalaman 9 meter.
Sebanyak 7 lintasan seismik berarah timurlaut-baratdaya dan 15 lintasan berarah barat laut ââŹâ tenggara telah dilakukan dan beberapa titik bor untuk memperkuat penafsiran jenis batuan di setiap lapisan penampang seismik.
Struktur geologi yang ditafsirkan dari seismik pantul ini adalah adanya suatu blok batuan yang seperti tersesarkan dan terdorong ke atas sebagai struktur diapir. Struktur diapir ini berkembang sangat baik di penampang seismik ke arah barat daya atau ke arah daratan dimana di sekitar pantainya batugamping ini membentuk undak batugamping.
Munculnya struktur diapir ini kemungkinannya dikarenakan bagian selatan dari zona Rembang ini terdapat suatu zona yang mempunyai anomali gaya berat negatif dan karena batugampingnya banyak terpatahkan sehingga sangat mudah diintrusi oleh sedimen yang mempunyai berat jenis kecil.

The study area is dominated by coral reef limestone of Paciran Formation of Rembang Zone. This coral reef limestone is responsible to form the beach terraces along the Tanjung Awar-Awar and Tuban beach and its surrounded. The formation of this coral reef limestone terraces closely related to vertical movement of these rocks units.
The study area is bathymetrically flat where the shallow part is on southwest (towards the beach) with 2 meters depth and the deeper part is to northeast part with 9 meters depth.
There are 7 seismic reflection lines of NE-SW and 15 lines of NW-SE have been done and some rocks drilling to emphasize the seismic sequences.
The interpretation of geological structure from seismic reflection shows a feature of rocks unit was faulted and intruded as diapiric structures. These features are well developed towards the beach where the terrace of coral reef limestone can be found on the beaches.
The formation of these diapiric structures are interpreted where on southward of the Rembang Zone there is a gravity negative anomalies and also due to the limestone were faulted and it seems to be easy intruded by a sediment with low density.

Wheelchair Seating Assessment and Intervention: A Comparison between Telerehabilitation and Face-to-Face Service
This study compared outcomes of wheelchair seating and positioning interventions provided by telerehabilitation (n=10) and face-to-face (n=20; 10 in each of two comparison groups, one urban and one rural). Comparison clients were matched to the telerehabilitation clients in age, diagnosis, and type of seating components received. Clients and referring therapists rated their satisfaction and identified if seating intervention goals were met. Clients recorded travel expenses incurred or saved, and all therapists recorded time spent providing service. Wait times and completion times were tracked. Clients seen by telerehabilitation had similar satisfaction ratings and were as likely to have their goals met as clients seen face-to-face; telerehabilitation clients saved travel costs. Rural referring therapists who used telerehabilitation spent more time in preparation and follow-up than the other groups. Clients assessed by telerehabilitation had shorter wait times for assessment than rural face-to-face clients, but their interventions took as long to complete.
