In 1999, Medicare implemented a resource-based relative value unit (RVU) system for physician practice expense payments, and increased the number of services for which practice expense payments differ by site. Using 1998-2004 data, we examined RVU growth and decomposed that growth into resource-based RVUs, site of service, and service quantity and mix. We found that the number services with sit...

Grain and forage from corn plants vary in composition and digestibility due to genetics and numerous environmental factors. For decades, corn hybrids have been selected based on agronomics (yield, disease and insect resistance). In addition, hybrids have been developed or selected for specific traits desired in specialty markets (food manufacturing properties: popcorn, white color, waxy, high a...

Feeding habits of yellowfin seabream, Acanthopagrus latus was investigated in coastal waters of the Northern Persian Gulf. This investigation was conducted by monthly sampling of thirty fish from September 2011 through August 2012. Fish size ranged from 17.98 ± 2.07 to 32.31 ± 6.52 cm in total length and from 134.01 ± 45.62 to 720.46 ± 292.58 g in weight. The highest value of gastro-somatic ind...

The ethanol industry is expanding rapidly. This expansion in production of renewable energy also increases production of by-products. These byproducts, primarily distillers grains plus solubles (DGS), are utilized very efficiently by ruminants. When the starch in corn is fermented to produce ethanol, the remaining nutrients (protein, fat, fiber) are concentrated about 3-fold. Whereas DGS is an ...

Walkingstick cholla cactus (Opuntia imbricata [Haw.] DC) has been used in New Mexico as an emergency feed during drought for more than 100 years. Most reports present only the chemical composition of walkingstick cholla, and limited data exist regarding its feeding value. Three wethers (avg wt 65 6 7 kg) were fed a basal diet of mature blue grama hay (Bouteloua gracilis [HBK] Lag. ex Steud., 9....

Background: Tariff setting in healthcare is an important control knob affecting the quality, access and cost of services. As part of Iran Health Transformation Plan (HTP) in 2014, the relative value of health care and services was increased to motivate healthcare providers to deliver high quality services. This study aimed to examine the impact of HTP on health services tariffs. Methods: This ...

Surprising downshifts from more preferred (training incentive) to less preferred incentives (test incentive) are usually accompanied by emotional activation and suppression of conditioned behavior in rats. Two experiments were designed to determine whether consummatory behavior is similarly aVected by downshifts of equal proportions. Within limits, the degree of consummatory responding during i...

Arguments between adherents of different therapeutic models are often based on the assumption that empirical evidence is ultimately the judge of the merits of the respective approaches. The gathering of empirical evidence, however, is programmed by epistemological premises that in turn are not tested by "objective" demonstration but rather by their congruence with prevailing sociocultural value...
