RESUMO
Completing an augmentative and alternative communication (AAC) assessment is a complex process that involves many stakeholders and professionals. To help clarify professional roles and provide assessment guidelines, an AAC Assessment Personnel Framework was developed. This framework was adapted from the work of Beukelman, Ball, and Fager in 2008, which focused on general AAC needs (not just assessment) and concentrated specifically on adults. In contrast, the present model examines the assessment process for all individuals who require AAC. The following AAC assessment personnel are discussed: AAC finders, general practice SLPs, AAC clinical specialists, facilitators and communication partners, collaborating professionals, AAC research and policy specialists, manufacturers and vendors, funding agencies and personnel, and AAC/assistive technology agencies and personnel. Current barriers for successful assessment outcomes are discussed, and suggestions for addressing personnel-related barriers are explored.

fac-[RuII(Cl)(dpp)(L3)]+ (L3 = tris(pyrid-2-yl)methoxymethane (tpmm) = [1A]+ and tris(pyrid-2-yl)pentoxymethane (tppm) = [1B]+ and dpp = di(pyrazol-1-yl)propane) rapidly undergo ligand substitution with water to form fac-[RuII(H2O)(dpp)(L3)]2+ (L3 = tpmm = [2A]2+ and tppm = [2B]2+). In the structure of [2A]2+, the distorted octahedral arrangement of ligands around Ru is evident by a long Ru(1)-O(40) of 2.172(3) A and a large angle O(40)-Ru(1)-N(51) of 96.95(14) degrees . The remarkably short distance between O(40) of H2O and H(45a) of dpp confirms the heteroscorpionate ligand effect of dpp on H2O. [2B]2+ aerobically catalyzes methyl p-tolyl sulfide to methyl p-tolyl sulfoxide in 1,2-dichlorobenzene at 25.0 +/- 0.1 degrees C under 11.4 psi of O2. Experimental facts in support of this aerobic sulfide oxidation are the absence of H2O2 and the oxidative reactivity of the putative Ru(IV)-oxo intermediate toward methyl p-tolyl sulfide, 2-propanol, and allyl alcohol. This study provides the first documented example of aerobic-sulfide oxidation catalyzed by the remarkably labile heteroscorpionate Ru(II)-aqua complex without the formation of a highly reactive peroxide as an intermediate.
