Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment.
Having lived with the World Wide Web for twenty years, surfing the Web becomes a way of our life that cannot be separated. From latest news, photo sharing, social activities, to research collaborations and even commercial activities and government affairs, almost all kinds of information are available and processible via the Web. While people are appreciating the great invention, the father of the Web, Sir Tim Berners-Lee, has started the plan for the next generation of the Web, the Semantic Web....
The purpose of this Note is to provide an informed, plausible series of proved reserves and annual reserve changes by type for crude oil and natural gas (dry) that links these two different series of reserve estimates over the late 1970s. It describes the basic differences between the two published series of reserve estimates, explores the possible reasons for differences between the two series, a......
The timing of monthly bill payments could explain the pattern we observe, if the
timing happens to coincide with payday for most households. To the extent that the
timing of bill payments is non-discretionary, this explanation implies that the decline in
spending cannot be used to infer household preferences for timing of consumption.
Dewey’s discussion is of interest in part because it reflects a number of
common and reasonable intuitions about the boundaries of the aesthetic. I will
isolate the particular criteria that emerge from Dewey’s account and identify the
most plausible rationale for regarding each as a necessary condition for aesthetic
experience. I will then argue that the criteria, as they ought to be understood, do
not rule out everyday experiences like those I have described; and, indeed, that
there are strong reasons to include such experiences within the realm of the
We investigate for lunar cycle effects in stock returns for two reasons. First,
contemporary surveys confirm that a large part of the population, about 50 percent,
believes that strange behavior peaks around the full moon (e.g., Kelly, Rotton, and Culver
1996). If such behavior exists, it seems plausible that it influences investor behavior and
the resulting stock prices and returns. Note that, in contrast to existing evidence of lunar
effects on sporadic and extreme behavior, stock prices are powerful aggregators of
regular and recurring human behavior.
This abstract outlines a parser implemented in a connectionist model of short term memory and reasoning 1. This connectionist architecture, proposed by Shastri in [Shastri and Ajjanagadde, 1990], preserves the symbolic interpretation of the information it stores and manipulates, but does its computations with nodes which have roughly the same computational properties as neurons. The parser recovers the phrase structure of a sentence incrementally from beginning to end and is intended to be a plausible model of human sentence processing. ...
Our results are based on model simulations, and so the credibility of the ﬁndings
depends on the plausibility of our model. For the purpose of our results here, the two
cornerstones of our model are sticky wages and an estimated Taylor rule. That the
latter is a reasonable way to capture monetary policy has almost become axiomatic.
Sticky wages have also emerged in recent years as a key feature of models that ﬁt
