Functional Phonology, which makes a principled distinction between articulatory and perceptual representations, features, and constraints, can describe as well as explain the symmetries as well as the gaps in inventories of vowels and consonants. Symmetries are the language-specific results of general human limitations on the acquisition of perceptual categorization and motor skills. Gaps are t...

Despite modeling groundwater as a common property resource, existing economic analyses find that the quantitative difference between competitive and socially optimal groundwater management outcomes is negligible. Thus, in contrast to the public perception of groundwater overextraction and resource depletion, there appears to be no economic rationale for groundwater management. In this paper, we...

Groundwater is an important source of potable water because it is abundant and readily available in many locations and often requires little or no treatment. In 1995, groundwater accounted for approximately 20% of potable water use in the U.S., and approximately 50% of the U.S. population relied on groundwater for their source of drinking water. In most European countries, groundwater accounts ...

OBJECTIVE To develop methods for building corpus-specific sense inventories of abbreviations occurring in clinical documents. DESIGN A corpus of internal medicine admission notes was collected and instances of each clinical abbreviation in the corpus were clustered to different sense clusters. One instance from each cluster was manually annotated to generate a final list of senses. Two cluste...

Recent EU legislation is directed to reverse the upward trends in the concentrations of agricultural pollutants in groundwater. However, uncertainty of the groundwater travel time towards the screens of the groundwater quality monitoring networks complicates the demonstration of trend reversal. We investigated whether trend reversal can be demonstrated by relating concentrations of pollutants i...

Many of the world's megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that exten...

Professor of Agricultural Economics, Purdue University ewer than ten states tax the assessed value of business inventories as part of the property tax; Indiana is one of them. For years businesses have pressed the Indiana legislature to reduce or repeal this "inventory tax," but a concensus on its eradication has yet to be reached. Most recently, the 1999 session of the Indiana General Assembly...

Personality researchers have recently advocated the use of very short personality inventories in order to minimize administration time. However, few such inventories are currently available. Here I introduce an automated method that can be used to abbreviate virtually any personality inventory with minimal effort. After validating the method against existing measures in Studies 1 and 2, a new 1...
