Using Single-Case Participatory Action Research as a Methodology to Explore Appalachian Summer Camp Communities

Community educators have long known the value of direct experience in the learning process. Participatory action research extends this philosophy to the realm of research. This article examines the value of involving front line camp staff, members of the camp community in Appalachia as practitioner researchers with university scientists in studying the type and conditions of transformative learning in young adult camp staff. A young adult who was a camp community member assisted the researchers with methodology, data analysis, data interpretation, and dissemination of findings. This resulted in a more accurate, richer, and thicker description of the camp community member’s transformative learning experience. The benefits of involving practitioner researchers are examined, as well as promising practices for conducting participatory action research in community education environments.

Evaluation of Condensed Porcine Solubles as a Source of Supplemental Nitrogen in Corn-Based Finishing Diets for Yearling Steers

A feeding trial was conducted with 860-lb yearling steers fed 121 days to evaluate Condensed Porcine Solubles (Porcine Solubles) as a source of supplemental nitrogen for finishing cattle. Diets containing 5% soybean meal, 1.46% urea, and 2% or 4% Porcine Solubles were compared. When first offered, cattle did not want to consume feed containing the Porcine Solubles. Following adaptation, feed containing up to 4% Porcine Solubles was readily consumed. During the first 56 days, steers fed soybean meal gained faster and were more efficient than steers fed urea or Porcine Solubles. At the end of the trial there were no differences among the nitrogen supplements in feed intake, gain, or feed conversion. There were no significant differences in carcass weight or measures of carcass quality.

Effects of Chemical Composition on Forage Intake of Heifers Fed Hays of Different Species

Alfalfa, smooth bromegrass, and big bluestem hays harvested at two maturities differing by four weeks were fed at mature-to-immature hay ratios of 1:0, 2:1, 1:2, and 0:1 to yearling heifers in an experiment with a three 4 x 4 Latin square design with 14 day periods. Concentrations of in vitro digestible dry matter and crude protein were greater and concentrations of neutral detergent fiber, acid detergent fiber, and indigestible neutral detergent fiber (determined by either a manual method with a 96 hour incubation or an automated method with a 48 hour incubation) were less in alfalfa hay than in the two grass hays and in smooth bromegrass hay than in big bluestem hay. Concentrations of in vitro digestible dry matter and crude protein decreased whereas those of neutral detergent fiber, acid detergent fiber and indigestible neutral detergent fiber increased with increasing forage maturity. Consumptions of dry matter, digestible dry matter, in vitro digestible dry matter, and crude protein were greater for heifers fed alfalfa hay diets than those fed the two grasses. Consumptions of total neutral detergent fiber and indigestible neutral detergent fiber, determined by the automated method with a 48 hour incubation, were greater by heifers fed diets containing big bluestem than those fed alfalfa or smooth bromegrass diets. Consumptions of acid detergent fiber and indigestible neutral detergent fiber, determined by a manual method with a 96 hour incubation, were greater for heifers fed alfalfa or big bluestem hay diets than those of heifers fed smooth bromegrass diets. Consumption of dry matter, in vivo or in vitro digestible dry matter, crude protein, neutral detergent fiber, acid detergent fiber and automated indigestible neutral detergent fiber decreased as the mature-to-immature hay ratio decreased. Diet digestibility was not affected by forage species, but increased as the mature-toimmature hay ratio decreased. Fecal excretion of dry matter and neutral detergent fiber did not differ between forage species or mature-to-immature hay ratios. Forage dry matter intake expressed as a percentage of body weight was significantly related to the concentrations of in vitro digestible dry matter (r2=.14), crude protein (r2=.17), neutral detergent fiber (r2=.20), and manual indigestible neutral detergent fiber (r2=.18) of the hays and the concentration of digestible dry matter of the diets (r2=.43).

Estimating the Value of Source Verification in Iowa Feeder Cattle Markets

Source verification and pooling of feeder cattle into larger lots resulted in higher selling prices compared with more typical sales at a southern Iowa auction market. After accounting for higher prices due to larger lot sizes, cattle that received a specified management program and were source verified as to origin received additional price premiums. The data do not distinguish between the value of the specific management program and the value of the source verification process. However, cow-calf producers participating in the program took home more money.

Proceedings of the 13th Annual Biochemical Engineering Symposium

The symposium reported here was the thirteenth of a series devoted to talks by students on their biochemical engineering research. The first, third, fifth, ninth, and twelfth were at Kansas State University, the second and fourth were at the University of Nebraska–Lincoln, the sixth was in Kansas City and was hosted by Iowa State University, the seventh and tenth were at Iowa State, and the eighth and eleventh were at the University of Missouri–Columbia and Colorado State University, respectively. All symposia have been followed by proceedings edited by faculty of the host institution. Because final publication usually takes place elsewhere, papers here are brief, and often cover research in progress. ContentSequential Utilization of Mixed Sugars by Clostridium acetobutylicum, B.

Blade guard for rotary lawn mowers

A blade guard for rotary lawn mowers comprising a plurality of spaced apart elongated members which extend longitudinally in the intended direction of travel of the mower device. The space between the forward ends of the elongated members and the forward end of the mower cowling is open and free from obstructions to permit the grass to be sucked upwardly for cutting by the mower blade. The elongated members have varying lengths to define an effective area substantially the same as the area defined by the unsharpened center portion of the mower blade when rotating so that the sharpened ends of the blade extend outwardly beyond the effective area of the guard means. The guard means is hinged to the mower cowling to permit convenient cleaning of the mower. An ignition interlock means is also connected to the guard.
