Spatial Segregation in Demography: A Short Review

  Abstract. Spatial has always been an inherent component of demography, and demographic processes are inherently spatiotemporal. Recognizing the importance of spatial in general and spatial segregation in particular in demographic analysis has created new positions in demography and its conceptual and analytical frameworks. The notion of spatial segregation refers to the distribution of social...

The perceptual segregation of simultaneous auditory signals: pulse train segregation and vowel segregation.

In the experiments reported here, we attempted to find out more about how the auditory system is able to separate two simultaneous harmonic sounds. Previous research (Halikia & Bregman, 1984a, 1984b; Scheffers, 1983a) had indicated that a difference in fundamental frequency (F0) between two simultaneous vowel sounds improves their separate identification. In the present experiments, we looked a...

Measuring Segregation∗

We propose a set of basic properties that any reasonable segregation index should have. We then fully characterize the class of segregation indices that satisfy these basic properties. We show that every such index has a particular simple form. Finally, we show that with one rarely used exception, each index defined in the literature violates one or more of our basic properties.

Transcriptional segregation

Soluble prion protein makes mice unsteady. Li nd qu is t/A A A S version: the infectious, detergent-resistant, plaque-forming fibrillar PrP Sc seen in diseased brains of scrapie-infected sheep and mad cows. Instead, Jiyan Ma, Robert Wollmann (University of Chicago, Chicago, IL), and Susan Lindquist (MIT, Cambridge, MA) point the finger at cytosolic PrP. Minor misfolding events probably lead to ...
