Do states engage in infrastructure expenditure competition to attract new economic activity? Economic theory is inconclusive on the matter. States might respond to increased infrastructure spending in competitor states by increasing their own infrastructure spending. Conversely, states may decrease spending in the presence of positive spillovers from(More)
Direct behavioral observation and motility monitoring procedures provide reliable data, and both are appropriate for sleep/wake state measurements starting immediately after birth. Using these procedures, newborn rats, rabbits, and humans were found to have a greater amount of quiet sleep on the day of birth rather than 24 hr later. Changes in active sleep(More)
Humans are remarkably versatile with regard to the recognition of hand-or machine-printed letters. More than 100 fonts (styles of type) are in common use throughout the United States, and even letters in new or unusual fonts can be recognized with very little effort (see Fig. IX-1). When hand-printed (script) letters are also considered, we realize that(More)
Previous studies in human infants, rabbits, and rats have shown that states of sleep and wakefulness can be reliably identified from motility signals produced by respiration and body movement. Thoman has described a computer-scoring algorithm for automated scoring of behavioral states from motility signals in human infants. In the present studies, we report(More)
As an animal swims through the Lashley III maze, an observer types into a Macintosh computer the path taken. The computer program, Observe Software, then breaks the string of choices into two-step sequences and counts the number of such sequences. These data are then sent to a spreadsheet, where the sequences are sorted into forward and backward responses.(More)
