Categories are the most basic structures by which human beings understand, describe, and communicate phenomena and related information about the world (Lakoff, 1987). Geographers construct categories to conceptualize, define, interpret and communicate geographic phenomena, for instance, land cover, vegetation types, soil types, regions of economic growth, and many others. In general, categories...

This study investigated the effects of manipulating the load components of aerobic training sessions on the physical performance of rats. To achieve this purpose, adult male Wistar rats were divided into four groups: an untrained control (CON) group and training groups with a predominant overload in intensity (INT) or duration (DUR) or alternating and similar overloads in intensity and duration...

Associative memory for auditory-cued events involves specific plasticity in the primary auditory cortex (A1) that facilitates responses to tones which gain behavioral significance, by modifying representational parameters of sensory coding. Learning strategy, rather than the amount or content of learning, can determine this learning-induced cortical (high order) associative representational pla...

We study self-selection into contests among a large population of heterogeneous agents. We show that entry into the “richer” contest (in terms of show-up fees, number or value of prizes) is non-monotone in ability. Entry into the more meritocratic (i.e., discriminatory) contest exhibits two interior extrema. Other testable predictions of our model are: 1) All else equal, the more meritocratic c...

It has been shown in previous communications (1, 2) that an influence transmitted in the milk of certain lactating female mice was effective in influencing the growth of lymphoid leukemias (lines LL449 and and P1543) in mice normally refractory to their growth. This "susceptibility influence" was found to be present dur ing the first l0 days of the lactation period. The influence was found to b...

ed, coded, and/or incomplete reflection of the object itself. Mental transformations are viewed as operations on the structure of a propositional network that lead to changes in the way the representation can be used. Investigators have attempted to devise procedures that would permit inferences as to whether analog or propositional processing is being used in mental rotation tasks, despite the...

INTRODUCTION Flexible ureteroscopes are expensive and delicate instruments that are integral in the offering of a minimally invasive technique of diagnosis and treatment of urolithiasis. Published literature has identified the importance of early damage recognition in preventing frequent use of the scope that would lead to further damage and high repair and replacement costs. Our study was desi...
