Spam comprises at least 60% of the public web, and search engine companies invest considerable effort in rejecting these apparently useless pages. But how bad are spam pages in search results? Can spam be dealt with as a side-effect of dealing with page utility, or is the relationship more complex? Thirty-four volunteer judges rated selected individual documents first on usefulness to a specifi...

E very aspect of higher education today is pressed to become more accountable and more transparent. The field of continuing education (CE) is no different. As CE professionals, responsible for the operations of university-based CE units, we are constantly challenged to use data and “evidence” to make and justify decisions. Indeed, one measure of the professionalization of a field is its ability...

Gelatin given by vein to doubly depleted dogs (anemic and hypoproteinemic) gives no immediate toxic response, no anaphylactoid reactions, and may contribute something to the building of new hemoglobin and plasma protein. Gelatin given by vein during 1 to 2 weeks (total 3 to 17 gm. per kilo) usually causes serious disturbances-inhibition of blood protein production, signs of intoxication, much w...

A miniature flexible fiberoptic bronchoscope (FFB) (Olympus BF-N20) (2.2 mm diameter) was applied to 53 children (20 female subjects) ranging in age from 3 months to 15 years (mean, 4.19 years). Most common indications for bronchoscopy included stridor or weak cry and persistent wheezing or cough unresponsive to inhaled bronchodilators, chest physiotherapy, steroids, and antimicrobial agents. T...

This paper develops the concept of usefulness in the context of supervised learning. We argue that usefulness can be used to improve the performance of classification rules (as measured by error rate), as well to reduce their storage (or their derivation). We also indicate how usefulness can be applied in a dynamic setting, in which the distribution of at least one class is changing with time. ...

The belief that elections reduce rent seeking by government officials is widely held, likewise the belief that rent seeking decreases as elections are less subject to corruption. In this paper we develop and test a model in which these beliefs are carefully examined. Our model indicates that, while elections may provide a disincentive for rent seeking, this disincentive (1) need not actually ma...

 In this paper, we consider a flexible skew-generalized normal distribution. This distribution is denoted by $FSGN(/lambda _1, /lambda _2 /theta)$. It contains the normal, skew-normal (Azzalini, 1985), skew generalized normal (Arellano-Valle et al., 2004) and skew flexible-normal (Gomez et al., 2011) distributions as special cases. Some important properties of this distribution are establi...
