BOARD-INVITED REVIEW: Use of distillers by-products in the beef cattle feeding industry.

Abstract: The ethanol industry is expanding rap- idly. This expansion in production of renewable energy also increases production of by-products. These by- products, 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 concen- trated about 3-fold. Whereas DGS is an excellent pro- tein source for ruminants, the large supply and the price relative to corn make DGS an attractive energy source as well. This is especially important with re- duced availability and higher price of corn because of demand by the ethanol industry. A meta-analysis of 9 experiments, where various levels of wet DGS were fed to feedlot cattle, shows that wet DGS produced higher ADG and G:F compared with cattle fed corn-based diets

Planar-to-tubular structural transition in boron clusters: B20 as the embryo of single-walled boron nanotubes.

Abstract: Experimental and computational simulations revealed that boron clusters, which favor planar (2D) structures up to 18 atoms, prefer 3D structures beginning at 20 atoms. Using global optimization methods, we found that the B20 neutral cluster has a double-ring tubular structure with a diameter of 5.2 A. For the B(-)20 anion, the tubular structure is shown to be isoenergetic to 2D structures, which were observed and confirmed by photoelectron spectroscopy. The 2D-to-3D structural transition observed at B20, reminiscent of the ring-to-fullerene transition at C20 in carbon clusters, suggests it may be considered as the embryo of the thinnest single-walled boron nanotubes.

"The policy exists but you can't really use it": communication and the structuration of work-family policies

Abstract: Although work-family benefits are increasingly important organizational policies, limited research addresses the impact of communication on benefit utilization. However, communication is significant because the perceived appropriateness of work-family benefits emerges through interaction. For example, when coworkers complain about "picking up the slack" for those using family leave, their discourse may impact future decisions of other workers regarding whether they utilize the work-family benefits available to them. We apply Giddens' (1984) Structuration Theory to examine organizational members' discursive responses to conditions (and contradictions) present in utilizing work-family benefits in a governmental organization. We argue the daily discursive practices of individuals can either reinforce or undermine formally stated work-family initiatives, and in turn discuss the implications of this "structuration" of policy.

The Children and Youth We Serve A National Picture of the Characteristics of Students With Emotional Disturbances Receiving Special Education

Abstract: This article provides a national perspective of children and youth with emotional disturbances (ED) served in special education using data from the Special Education Elementary Longitudinal Study and the National LongitudinalTransition Study—2. Data sources comprise teachers,school records, the students, and their parents. Results indicate that children and youth with ED live in households in which multiple risk factors exist for poor life outcomes. As a group, these children and youth have serious and multiple impairments that include an array of emotional disabilities, poor communication skills, and low academic achievement. There is a considerable gap between initial identification of problems and the onset of service delivery, a high rate of suspension and expulsion, and an unstable school environment. Parents of children and youth with ED work harder to secure services for their children and are less satisfied with services than parents of children in other disability groups. Implications of the find...
