OBJECTIVES This study examined and compared utilization of dental services by adult U.S. Hispanics 18 years and older in the years 1999 and 2006. METHODS Dental utilization data collected by telephone interviews by the state-based Behavioral Risk Factor Surveillance System (BRFSS) were analyzed. RESULTS In 2006, the state mean and median prevalence of adult Hispanics with dental visits duri...

A recent report by the Medicare Payment Advisory Commission to Congress indicated that the utilization of diagnostic imaging is growing more rapidly than that of any other type of physician service. This has engendered concern among those who pay for health care. In this article, the authors review the role of self-referral in driving up imaging utilization. A number of studies of the self-refe...

In this paper, we show how to assess human workload for continuous tasks and describe how operator performance is affected by variations in break-work intervals and by different utilizations. A study was conducted examining the effects of different break-work intervals and utilization as a factor in a mental workload model. We investigated the impact of operator performance on operational error...

We show a detail implementation for a linear time and space method, introduced in [3], to compute the length of a repeated suffix for each prefix of a given word p. This method is based on the utilization of the factor oracle [1] of p, which is deterministic acyclic automata accepting all subustrings of p. keyword: factor oracle, suffix link, repetition

This paper develops estimates of TFP growth adjusted for movements in unobserved factor utilization a panel 29 countries and up to 37 years. When changes are unobserved, the commonly used Solow residual mismeasures actual TFP. We use general equilibrium dynamic multi-country multi-sector model derive production function estimating equation that corrects usage. compare properties utilization-adj...

responses to sugars in dry or liquid formvary from study to study. when fed in proper amounts, sugars should not depress ruminalph, and there is some evidence that they actuallyhelp toprevent a drop in ph after consuming largemeals of concentrate by maintaining a highernumberoflactate-fermenting bacteria. adding sugars doesprioritize the need for rumen degraded protein (rdp).we all know, sugars...
