The Local Public Health System Assessment (LPHSA) in Mobilizing for Action through Planning and Partnerships (MAPP), and the Local Tool of the National Public Health Performance Standards Program (LT/NPHPSP)--which are one in the same-attempt to assess the capacity to provide the essential public health services. Both tools have been utilized in various public health practice settings; however, users have been challenged with the complexity of the tools and time and human resource investment necessary to complete them. The recent Journal of Public Health Management and Practice issue focus on MAPP provided several examples of LPHSA implementation, both as a component of MAPP and as a stand-alone activity in the context of performance standards. The uniqueness in our approach involved a collaborative between a community-based organization, a public health academic program, and a governmental public health agency which conducted the LPHSA in a manner that did not require actual modification of the tool itself, was practical and feasible, and was of benefit and value to all partners.

The synthesis, characterization, and incorporation in volatile metal-organic chemical vapor deposition (MOCVD) precursors of a new class of linked beta-ketoiminate-polyether-beta-ketoiminate ligands is presented. These ligands are designed to encapsulate alkaline-earth cations having low charges and large ionic radii. Barium complexes having the general formula Ba[(RCOCHC(R')N)2(R")] (R = tert-butyl or CF3; R' = tert-butyl, methyl, or CF3; R" = -(CH2CH2O)4CH2CH2- or -(CH2CH2O)5CH2CH2)-) were prepared and characterized by 1H and 13C NMR spectroscopy, elemental analysis, and mass spectrometry. Single-crystal X-ray diffraction analysis of 2,2,5,25,28,28-hexamethyl-9,12,15,18,21-pentaoxa-4,25-diene-6,24- diimino-3,27-pentacosadionatobarium(II) reveals a monomeric, nine-coordinate, tricapped trigonal prismatic coordination geometry. Single-crystal X-ray structural analysis of 1,1,1,24,24,24-hexafluoro-4,21-ditrifluoromethyl-8,11,14,17- tetraoxa-3,21-diene-5,20-diimino-2,23-tetracosadionatobarium(II).2DMSO reveals a monomeric, ten-coordinate, distorted tetracapped trigonal prismatic coordination geometry. Volatility data are presented for these barium complexes, demonstrating viability as MOCVD precursors. In addition, it is demonstrated that thin epitaxial films of BaTiO3 can be grown on (001) MgO by low-pressure MOCVD techniques using one of these barium complexes and Ti(dipivaloylmethanate)2(isopropoxide)2 as precursors.

Far IR optical properties have been measured for smoke from diesel fires. Concentrations of both gaseous and particulate combustion products have been measured and chemical species contributing to the optical effects identified. To obtain these results, a variety of sampling instruments were lofted into large plumes on a mobile and open structure. The smoke plumes of diesel fires have been found to consist largely of carbonaceous material (in fibrous form) and heavy liquid hydrocarbons infused with the expected gaseous products of the combustion process. Strong attenuation at a wavelength of 10.6 microm is found to be due largely to the carbonaceous aerosol. The absorption coefficient is typically ~500 km(-1) at 10 m from the source with a variable but often comparable total scattering coefficient. The extinction coefficient, normalized to the mass density of the aerosol in a unit volume of space, is found to be 1.2 m(2)-g(-1) with an estimated variance of 20%. luctuational spectra of the attenuation follow a form similar to turbulence spectra.
