Examination of polished sections of manganese micronodules
from metalliferous sediments from the Bauer Deep reveals sequences
of ferromanganese deposition which are consistent for micronodules
from a single sediment sample and imply a common depositional
history for members of such assemblages. The relatively simple
'stratigraphy' of manganese micronodules, as compared to...

As program participants integrate new knowledge and understanding into previous standards regarding attitudes or perceptions, these altered standards violate the assumption of consistency inherent to the pretest-posttest method for measuring change over time. If this violation, or response-shift bias, is not controlled results can be misleading, which carries serious implications...
Psychological theory of social cognition and Buddhist philosophy of cognition suggest that people's actions should determine their impressions of future events. In psychology, several studies have shown that behavior can activate constructs and thereby influence one's perception. However, they do not address prosocial behavior, a specific concern of Buddhist philosophy...
This paper investigates the nature of disputants'
stories within the context of divorce mediation. Tapes

A number of thinkers are becoming increasingly persuaded
that our anthropocentric view of nature is inadequate, that we
need a "new morality" with regard to the environment. In this
essay, I argue that an alternative to anthropocentricism is
available to us now-and has been since at least 1836. I look...
Threshold-based time of arrival (TOA) estimation is a technique for high-precision indoor localization. Existing threshold selection methods, such as xed thresh- old and normalized threshold methods, do not consider the signal-to-noise radio (SNR) value at the receiver. This is not desired for high-precision positioning. A proper threshold value depends on...
Contaminants can exist in a wide range of states in aqueous environments, especially in surface waters. They can be freely dissolved or associated with dissolved or particulate organic matter depending on their chemical and physical characteristics. The freely dissolved fraction represents the most bioavailable fraction to an organism. These freely...
