Expanding upon work by Diessel & Tomasello (2005, hereafter D&T) and Gries (to appear), 1 this study explores particle positioning in child language as a gradual cognitive-pragmatic development based on statistical distribution of input. The phenomenon of particle position alternation is peculiar insofar as it defines a category of combinations which show syntactic variation without concomitant...

OLAP cubes are a powerful database technology to join tables and aggregate data to discover interesting trends. However, OLAP cubes exhibit limitations to uncover fractional relationships on a measure aggregated at multiple granularity levels. One prominent example is the percentage, an intuitive probablistic metric, used in practically every analytic application. With such motivation in mind, ...

AETIOLOGY: PSYCHOLOGICAL FACTORS The authors mention that significant psychological symptoms prevail in IBS, particularly among patients referred to gastroenterology clinics. It is true that studies have shown that 54%–94% of patients seen in tertiary referral centres meet the criteria for at least one primary psychiatric disorder. However, only 25%–30% of patients with IBS actually seek care, ...

This paper introduces a parsimonious methodology for measuring liquidity costs by parameterizing the relationship between price and order flow. Unlike the effective spread, our liquidity measure does not assume the midpoint of the spread equals the true price. We find that the marginal price impact of order flow declines rapidly and more liquid firms do not necessarily have lower liquidity cost...

Prediction equations for pork carcass lean percentage are widely used in Extension, teaching, and research. Prediction equations using carcass or live animal measurements are used in carcass contests, live animal evaluation, and marketing. Fat–free lean gain is used to estimate the daily lysine requirements for pigs in swine nutrition guides. The use of inaccurate equations has substantial econ...
