ESTIMATING REVENUE-CAPTURE POTENTIAL ASSOCIATED WITH PUBLIC AREA RECREATION

A traditional contingent valuation approach and the “"trip response method"” were examined as potential techniques for measuring public area recreation revenue-capture potential. Empirical results suggest that both methods are useful for assessing revenue-capture potential. Additional research on alternative methods for assessing recreation revenue-capture potential is encouraged.Resource /Energy Economics and Policy,

A PROPOSED METHODOLOGY FOR ESTIMATING ECOREGIONAL VALUES FOR OUTDOOR RECREATION IN THE UNITED STATES

This paper provides a methodology for the estimation of recreational demand functions and values using an ecoregional approach. Ten ecoregions in the continental US were defined based on similarly functioning ecosystem characters. The individual travel cost method was employed to estimate the recreational demand functions for activities such as motorboating and waterskiing, developed and primative camping, coldwater fishing, sightseeing and pleasure driving, and big game hunting for each ecoregions. Estimates of per trip net income value range from $12.93 to$218.38 while per day estimates range from $4.31 to$109.19. While our ecoregional approach differs conceptually from previous work, our results appear consistent with the previous travel cost method valuation studies.

Outdoor Recreation Constraints: An Examination of Race, Gender, and Rural Dwelling

We assess whether traditionally marginalized groups in American society (African-Americans, women, rural dwellers) perceive more constraints to outdoor recreation participation than other groups. A series of logistic regressions are applied to a national recreation survey and used to model the probability that individuals perceive certain constraints to participating in outdoor recreation activities. Twelve constraints related to health, facilities, socioeconomic standing, and other personal factors are examined for both participants and nonparticipants of outdoor recreation. We model the probability that individuals report being constrained in participating in their favorite activities as a function of race, gender, and rural residence. In addition, we control for income, age, regional differences, and activity groupings. Of the three groups examined, women are most likely to feel constrained--for instance, by personal safety concerns, inadequate facilities and information, insufficient funds, and outdoor pests. Race is not a significant predictor of constraints for participants, but nonparticipating African-Americans are more likely than whites to feel personal safety concerns inhibit their outdoor recreation opportunities. Rural residence does not appear to be an important factor among either participants or nonparticipants in explaining the probability that an individual feels constrained in outdoor recreation participation

EFFECTS OF RESERVOIR AQUATIC PLANT MANAGEMENT ON RECREATIONAL EXPENDITURES AND REGIONAL ECONOMIC ACTIVITY

Exotic aquatic plant management is a major concern for public reservoir management in many regions of the United States. A study was conducted to measure the effects of alternative aquatic plant management strategies on recreational expenditures and regional economic activity. The study areas was Lake Guntersville, Alabama, and the local economy surrounding the lake. Lake Guntersville is one of the largest reservoirs in the Tennessee Valley Authority system. Results suggested the relatively moderate levels of aquatic plant control are associated with the highest levels of recreation-related economic effects on the economy surrounding Lake Guntersville.Aquatic plants, Input-output analysis, Public reservoir management, Recreational expenditures, Regional economic activity, Resource /Energy Economics and Policy,

AN ANALYSIS OF WILLINGNESS TO PARTICIPATE IN WILDERNESS OR OTHER PRIMITIVE AREAS

A logit model was used to determine the major factors explaining willingness to participate of an individual in the wilderness or other primitive area visits. The results of the study showed that education and environmental awareness were in wilderness participation decision. Demographic variables like age, race, and sex also were statistically significant and emerged as important policy variables in defining wilderness participation behavior. Characteristics of wilderness areas like crowdness, pollution, and poor management failed to produce any significant impacts in the decision making process of wilderness area visit.wilderness or other primitive area visits, policy variables, demographic characteristics, participation behavior, Consumer/Household Economics,

OUTDOOR RECREATION TRENDS AND MARKET OPPORTUNITIES IN THE UNITED STATES

In 1994 and 1995, the National Survey of Recreation and Environment (NSRE) was accomplished by interviewing approximately 17,000 Americans over age 15 in random-digit-dialing telephone samplings. The primary purpose was to learn about the outdoor recreation activities of people over age 15 in the United States. They were asked about their participation in 62 specific recreation activities.Resource /Energy Economics and Policy,

Children\u27s Time Outdoors: Results from a National Survey

Abstract In the past decade, much has been said and written about American children’s declining outdoor leisure time. These claims are confounded by the absence of a baseline for detecting trends in children’s activities and time spent outdoors. The USDA Forest Service initiated a general population telephone survey, the National Kids Survey, to address this issue. This paper summarizes data collected during the first phase of this project (2007-2009). Results suggest that most children across all demographic groups are spending a substantial amount of time outdoors daily. Interaction with the natural environment varies as playing/hanging out, physical activities, and technology-centered activities appear to be more popular than nature-based activities. Future research efforts should build on these initial data and continue to monitor children’s outdoor activities patterns across diverse populations

The Use of Haplotypes in the Identification of Interaction between SNPs

Although haplotypes can provide great insight into the complex relationships between functional polymorphisms at a locus, their use in modern association studies has been limited. This is due to our inability to directly observe haplotypes in studies of unrelated individuals, but also to the extra complexity involved in their analysis and the difficulty in identifying which is the truly informative haplotype. Using a series of simulations, we tested a number of different models of a haplotype carrying two functional single nucleotide polymorphisms (SNPs) to assess the ability of haplotypic analysis to identify functional interactions between SNPs at the same locus. We found that, when phase is known, analysis of the haplotype is more powerful than analysis of the individual SNPs. The difference between the two approaches becomes less either as an increasing number of non-informative SNPs are included, or when the haplotypic phase is unknown, while in both cases the SNP association becomes progressively better at identifying the association. Our results suggest that when novel genotyping and bioinformatics methods are available to reconstruct haplotypic phase, this will permit the emergence of a new wave of haplotypic analysis able to consider interactions between SNPs with increased statistical power.</p
