Mentoring New Faculty: An Appreciative Approach
During this period of dramatic social and institutional change in higher education, positive induction and ongoing support for early-career and faculty members new to the campus community is essential. Disparities remain in the recruitment, development, retention, and promotion of diverse faculty, in large part because of the lack of mentoring. The purpose of this article is to enhance approaches for supporting early-career and otherwise new faculty members. Based upon the principles and processes of Appreciative Inquiry, the Appreciative Mentoring Model is presented. Each of the Appreciative Inquiry “D-phases” is described in detail together with research-based best practices that can be employed in mentoring. Prompts, questions, and specific examples designed to support the growing need for a more collaborative, fluid, dynamic, and transformative approach to mentoring are provided.
Influence of Bi2O3 content on the crystallization behavior of TeO2-Bi2O3-ZnO glass system
Glass ceramic materials with composition 75TeO2-xBi2O3-(25-x)ZnO (x = 13, 12, 11) possessing transparency in the near- and mid-infrared (MIR) regions were studied in this paper. It was found that as the Bi2O3 content increased in the glass composition, the observed crystallization tendency is enhanced, and high crystal concentrations were obtained for the glasses with high Bi2O3 content while maintaining transparency in the MIR region. Crystal size in the glass ceramic was reduced by adjusting the heat treatment conditions; the smallest average size obtained in this study is 700 nm. Bi0.864Te0.136O1.568 was identified using X-ray Diffraction (XRD) and found to be the only crystal phase developed in the glass ceramics when the treatment temperature was fixed at 335 °C. The morphology of the crystals was studied using Scanning Electron Microscopy (SEM), and crystals were found to be polyhedral structures with uniform sizes and a narrow size distribution for a fixed heat treatment regime. Infrared absorption spectra of the resulting glass ceramics were studied. The glass ceramic retained transparency in the infrared region when the crystals inside were smaller than 1 μm, with an absorption coefficient less than 0.5/cm in the infrared region from 1.25 to 2.5 μm. The mechanical properties were also improved after crystallization; the Vickers Hardness value of the glass ceramic increased by 10% relative to the base glass

Main Group Metal Halide Complexes with Sterically Hindered Thioureas. XVI. The Synthesis, Characterization, and Crystal Structures of Two New Complexes Of 1,3-dimethyl-2(3H)-imidazolethione with Indium Trihalides
In an attempt to prep. complexes analogous to the bis-dmit adducts of Group 15 trihalides [dmit = 1,3-dimethyl-2(3H)-imidazolethione], In(dmit)2X3 (X = Cl, Br) were synthesized and characterized. The crystal and mol. structures for both of these compds. showed a distorted trigonal bipyramidal configuration with the thiones and one halide occupying equatorial positions and the two remaining halides arranged in a near-linear X-In-X axial grouping (X = Cl, Br). This stands in contrast to the dimeric distorted octahedral structures obsd. for BiCl3(dmit)2 and SbCl3(dmit)2. The far-IR and laser-Raman spectra as well as soln. state proton and solid state 13C NMR spectra are reported
