Eye movements were monitored while participants performed a change detection task with images of natural scenes. An initial and a modified scene image were displayed in alternation, separated by a blank interval (flicker paradigm). In the modified image, a single target object was changed either by deleting that object from the scene or by rotating that(More)
The purpose of the present study was to investigate the degree to which foveal information is necessary for object identification. To explore this question, we used an artificial moving scotoma paradigm to eliminate a region of a currently viewed display in real time as a function of eye position. Subjects examined linear arrays of four line drawings of(More)
In this paper, we explore the increasingly significant role of human capital in regional development by presenting a number of hypotheses about the nature and extent of regional occupational specialization and exploring these with data analysis on national trends and on the Minneapolis/St. Paul metropolitan area. Nationally, we find that a region's(More)
Economic, political, cultural, and environmental distinctiveness may attract high-quality workers and firms as well as reflect a region's export viability. We hypothesize that local consumption activity can be a source of such distinctiveness and thus of long-term growth and stability, and that specialization does not reflect export activity alone.

Urban geographers conceptualize the distribution of economic activity across city systems in terms of hierarchy, where functions are related to size, and specialization, where places compete against each other for functional primacy. Using occupational data, we explore the salience of each for U.S. metropolitan areas. We find that large, urbanized places —(More)
Let us know how access to this document benefits you. Abstract This study examines the criteria which help academics receive National Institute of Health funds (NIH). The study covers 3,092 NIH recipients and non-recipients in the same department or institute at twenty-four universities. The universities are drawn from those below the top twenty in terms of(More)
