title: US Park recreation values (1968-2003): A review of the literature

authors: Kaval, Pamela

subjects: consumer surplus values

abstract: The results of outdoor recreation consumer surplus studies for national parks, national forests, state parks and state forests in the United States from 1968 through 2003 are compared and analyzed across activity type, locational region, and park designation. The resulting data set includes 1,229 observations, spanning 36 years, 28 types of activities, and 106 locations. All consumer surplus data were converted to 2006 United States dollars per person per day for comparison purposes. It was discovered that activity and park type played a significant role in consumer surplus values. Activities such as mountain biking, windsurfing, and rock-climbing were among the highest valued activities while visiting environmental education centers was the lowest. When comparing park types, it was found that on average, activities at National Parks had higher values than national forests, state parks, or state forests. This meta-analysis is the most extensive literature review in the history of non-market consumer surplus values for outdoor recreation in the United States ever conducted and should prove beneficial to anyone seeking information on outdoor recreation studies as well as those wishing to conduct a benefit transfer analysis for their own land management area.

title: Critical sets of 2-balanced Latin rectangles

authors: Cavenagh, Nicholas J.

subjects: Mathematics

abstract: An (m, n, 2)-balanced Latin rectangle is an (Formula presented.) array on symbols 0 and 1 such that each symbol occurs n times in each row and m times in each column, with each cell containing either two 0’s, two 1’s or both 0 and 1. We completely determine the structure of all critical sets of the full (m, n, 2)-balanced Latin rectangle (which contains 0 and 1 in each cell). If m, (Formula presented.), the minimum size for such a structure is shown to be (Formula presented.). Such critical sets in turn determine defining sets for (0, 1)-matrices.

title: Lake Rotokakahi water quality update 1990-2011

authors: Butterworth, Joseph

subjects: Lake Rotokakahi

abstract: Lake Rotokakahi is an Iwi-owned lake administered by the Lake Rotokakahi Board of Control on Behalf of lake owners who are descendants from the Ngāti Tumatawera and Tūhourangi hapū of Te Arawa. It is mesotrophic (moderate water quality) lake with an area of 4.4 km² comprised of exotic forestry (57.1%), pasture (26.3%) and regenerating indigenous forest/scrub (16.6%).
