Recreation is one of the ecosystem’s secondary values of a well conserved natural ecosystem, associated with the direct use individuals make of these natural assets. In this paper we define and estimate the total economic recreation value to visitors of a particular natural area, a national park. An on-site individual observation Travel Cost Model, Count Data distributions, and a version of hyp...

2. Phaistos Disk 360 This version of the system (Figure 2) was developed for, and is installed at, the information office of the Municipality of Heraklion in Crete. City visitors can interact with a largescale digital recreation of the Phaistos Disc, one of the most famous archaeological findings in Crete. The original clay disc, dating back to c. 1700 BC., is 16 cm in diameter and its two side...

ecreation managers make and act on decisions, often implicit, about the conditions, management approaches, and visitor experiences that are most appropriate for the individual recreation areas they administer. As demand for recreation, particularly in wilderness, backcountry, and wild river settings, has increased, such decisions have become more difficult, complex, and contentious. We believe ...

The purpose of this study was to use the Eccles’ expectancy-value model of choice as a framework to examine university students’ expectancy beliefs and task values in exergaming systems compared to those in physical education activities. Two hundred and thirty two first-year undergraduate students at the Democritus University of Thrace completed questionnaires assessing their expectancy-related...

When economists first turned to applied benefit-cost analysis in the 1930s and 1940s, prices were the only widely accepted measure of benefits. Perhaps surprisingly, economists did not consider measures like consumer surplus, which seemed quite foreign. Consequently, when they turned to nonmarket valuation for goods like outdoor recreation, their constructed demand curves seemed less informativ...

Coastal recreation and water quality are major contributors to human well-being in coastal regions. They can also interact, creating opportunities for ecosystem based management, ecological restoration, and water quality improvement that can positively affect people and the environment. Yet the effect of environmental quality on human behavior is often poorly quantified, but commonly assumed in...

Retinoblastoma is the most common primary intraocular tumor in children. The first sign that is often reported by parents is the appearance of recurrent leukocoria (i.e., "white eye") in recreational photographs. A quantitative definition or scale of leukocoria--as it appears during recreational photography--has not been established, and the amount of clinical information contained in a leukoco...

Physical activity in adult life may reduce prostate cancer risk. Data are scarce on the role of activity during early adulthood, as well as combined recreational and occupational physical activity on prostate cancer risk and mortality. We undertook a prospective study of 8,221 Icelandic men (born 1907 to 1935) in the population-based Reykjavik Study. At enrollment, between 1967 and 1987, the me...

Beach recreation values are often needed by policy-makers and resource managers to efficiently manage coastal resources, especially in popular coastal areas like Southern California. This article presents welfare values derived from random utility maximization-based recreation demand models that explain an individual’s decisions about whether or not to visit a beach and which beach to visit. Th...

This paper presents experimental research evaluation of the vibration exposure for the health risk prediction during vehicle operation. The vibration measurements were carried out on a recreational vehicle and two types of agricultural tractors. The vibration levels were measured for different surfaces and vehicle speed conditions. Based on the analysis of the results in the small agricultural ...
