A common task in the analysis of multi-environmental trials (MET) by linear mixed models (LMM) is estimation variance components (VCs). Most often, MET data are imbalanced (e.g., due to selection). The imbalance mechanism can be missing completely at random (MCAR), (MAR), or not random. If missing-data pattern was caused selection, it usually MAR. In this case, likelihood-based methods preferre...

The choice to conserve or be greedy in a commons dilemma may be influenced by the behavior of others and by pro-environmental values. Participants completed a measure of pro-environmental values one week before taking part in an Internet-based commons dilemma microworld consisting of a shared fishery with three computer-controlled virtual fishers whom participants believed to be real people. Th...

National park and related forest conservation efforts tend to emanate from core areas of the world and are often imposed on rurai people living on forest fringes in the least developed regions of lesser developed countries. We address the social and cuitural processes that ensue when center-originating conservation meets local people with their resource-dependent livelihoods, and how these vary...

Algorithmic skeletons in conjunction with list homomorphisms play an important role in formal development of parallel algorithms. We have designed a notion of homomorphism dedicated to bulk synchronous parallelism. In this paper we derive two application using this theory: sparse matrix vector multiplication and the all nearest smaller values problem. We implement a support for BSP homomorphism...

BACKGROUND Environmental health research employs a variety of metrics to measure heat exposure, both to directly study the health effects of outdoor temperature and to control for temperature in studies of other environmental exposures, including air pollution. To measure heat exposure, environmental health studies often use heat index, which incorporates both air temperature and moisture. Howe...

Land use of sewage sludge is the primary disposal method in Shanxi, accounting for 42.66% of all. To determine the ecological risk of heavy metals in sewage sludge, contents of seven heavy metals in sewage sludge from 9 municipal waste water treatment plants (WWTPs) that had the highest application for land use were determined. The order of the measured concentrations was: Zn > Cr > Cu > Ni > P...
