The accounting doctoral shortage: Accounting faculty opinions on hiring JD-CPAs as accounting educators
Objectives: Prior studies have noted that the number of PhDs in accounting are far below the number needed to meet program hiring needs. This paper reviews how the JD-CPA alternative credential is viewed by three academic accreditation bodies (SACS, ACBSP, and AACSB), the American Bar Association (ABA), and current accounting faculty at SACS-accredited institutions of higher education. Methods: An online survey was distributed to accounting educators at 439 institutions accredited by SACS, with 248 complete responses received. Individual demographics and institutional information were summarized statistically. Responses to two questions assessing inclination to hire an otherwise-qualified JD-CPA candidate using a 5-point Likert scale were analyzed by multiple regression with individual and institutional variables as predictors. Results: The study found that JD-CPA accounting educators are widely present in accounting faculties. Responses to the opinion questions indicated a substantial willingness to hire JD-CPAs, albeit with significant differences based on institution type, faculty rank, and possession of a Ph.D. Conclusion: This study demonstrates general willingness among current accounting faculty to consider JD-CPAs for tenure-track accounting faculty positions while still expressing a preference for candidates with a Ph.D. and with notable reservations from certain demographic segments of the accounting academe

Mohave rattlesnake (Crotalus scutulatus) identification revisited
Crotalus scutulatus (Mohave rattlesnake) is a clinically significant pit viper broadly distributed across much of the arid southwestern United States and mainland Mexico. Identification of C scutulatus is a concern among emergency medical service and emergency department personnel owing to its reputation for severe envenomations and difficulty in visually differentiating between C scutulatus and other species, primarily Crotalus atrox (western diamond-backed rattlesnake). We contrast distinctive characteristics of C scutulatus, C atrox, and 3 other sympatric species: Crotalus molossus, Crotalus ornatus, and Crotalus viridis (western and eastern black-tailed rattlesnakes and prairie rattlesnake, respectively). Greenish coloration eliminates C atrox but does not confirm C scutulatus. Obvious coarse and fine speckling of the dorsal pattern and a pale postocular stripe intersecting the mouth characterize C atrox. Dorsal speckling is insignificant or absent in the other species, whereas the pale postocular stripe passes above the mouth in C scutulatus and C viridis and is absent in C molossus and C ornatus. Tails boldly ringed with alternating black and white or contrasting shades of gray are shared by C atrox and C scutulatus, respectively, but a lack of boldly ringed tails characterizes the other species. The proximal rattle segment is yellow and black, or entirely yellow, in C scutulatus but black in the others. The most reliable visual identifications are based on evaluations of multiple traits, all of which are variable to some extent. Traits such as tail ring width and the size and number of crown scales have frequently been overemphasized in the past.Open access articleThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Distribution of the superconducting critical current density within a Gd–Ba–Cu–O single grain
Abstract: The magnitude of the maximum trapped magnetic field in a bulk, single-grain superconductor is a key performance figure of merit. This is determined, generally, by the magnitude of the critical current density, Jc, and the length scale over which it flows. As with all type-II superconductors, Jc is related closely to the microstructure of the superconducting material and, in the case of RE–Ba–Cu–O [(RE)BCO, where RE is a rare-earth element or yttrium] single grains, RE2BaCuO5 (RE-211) inclusions in the superconducting REBa2Cu3O7−δ (RE-123) phase matrix are key microstructural features that act effectively as flux pinning centres. Although the distribution of RE-211 in single-grain bulk superconductors has been studied extensively, the variation of Jc within a given sample has been much investigated much less thoroughly. A detailed experimental understanding of the variation of Jc in these technologically important materials, therefore, is required given the growing popularity and significance of numerical techniques for modelling the behaviour of type-II bulk superconductors. Here we report a systematic investigation of the correlation between Gd-211 particle density and sample porosity, which are microstructural features, and Tc and Jc in a Gd–Ba–Cu–O bulk, single grain fabricated using a buffer layer and a supply of additional liquid phase. This was performed by cutting the sample into numerous sub-specimens of approximate dimensions 1.8 × 2.8 × 1.5 mm3. We observe that Jc decreases with distance from the seed, although more strongly with distance along the c-axis than along the a–b plane. In contrast to what might be expected given the assumed contribution of RE-211 inclusions to flux pinning, we find no evidence of a clear correlation between the local RE-211 precipitate density and local critical current on a length scale of mm. We observe that the porosity of the sample is a more dominant factor in determining the distribution of Jc within a single grain
