Kautz, in the above paper' has presented a method of correcting single errors in SIB3 codes that does not displace the count by more than two counts in the counting sequence, assuming the two most significant bits are correct. This paper presents a correction method that does not require the two most significant bits to be correct and does not displace the count by more than one in the counting...

Using contemporary data for an extensive sample of 1020 Indian firms, this paper investigates the impacts that size and age of firms have on firm-level productivity and profitability. In India older firms are found to be more productive and less profitable, whereas the larger firms are, conversely, found to be more profitable and less productive. These performance differences are explained as a...

Previously published estimates of the area of the Peru upwelling ecosystem vary by more than an order of magnitude. In an effort to improve this situation, we used a 24-month sequence of SeaWiFS satellite images of chlorophyll in the surface water off Peru from 51S to 18.51S during September 1997–August 1999 to estimate the size of the nutrient enhanced productive habitat associated with the up...

Accelerating rates of species extinction have prompted a growing number of researchers to manipulate the richness of various groups of organisms and examine how this aspect of diversity impacts ecological processes that control the functioning of ecosystems. We summarize the results of 44 experiments that have manipulated the richness of plants to examine how plant diversity affects the product...

Trichotillomania (TTM) is a psychiatric disorder characterized by an irresistible urge to pull out one's hair. Currently there are no FDA approved treatments for TTM, which makes it difficult for clinicians to select an appropriate therapeutic plan. The clinical studies that have been performed do not provide sufficient or consistent evidence regarding which drug classes should be administered....

the normal and lateral line cycloid scales of the native species garra rossica (nikol’skii, 1900), one of the most common and poorly known cyprinid fish in south-eastern iran have been subjected to the scanning electron microscopy technique in order to study their detailed structure. normal scale below the dorsal fin showed a clearcut demonstration between the anterior and posterior region with...

This study extended the work of Sorensen and Pilgrim (2002) by examining the institutional affiliations of authors in leading criminology and criminal justice journals in the subsequent five-year period after their study. Additionally, this study replicated Fabianic's (2002) study, by assessing the average publications of the faculty at the most productive criminal justice graduate programs. Th...

CONTEXT Common pain conditions appear to have an adverse effect on work, but no comprehensive estimates exist on the amount of productive time lost in the US workforce due to pain. OBJECTIVE To measure lost productive time (absence and reduced performance due to common pain conditions) during a 2-week period. DESIGN AND SETTING Cross-sectional study using survey data from the American Produ...
