Only a handful of engineering luminaries know what it feels like to get “The Call” from IEEE Spectrum senior editor Tekla S. Perry. It's rite passage, vital part the process being selected by as Medal Honor recipient. This year was Mr. Internet himself, inimitable and always dapper Vint Cerf, you can read Perry's profile him on page 24.

Abstract This article suggests that global environmental assessments (GEAs) may be a potent means for making the humanities more consequential outside universities. So far most GEAs have been led by geoscientists, with mainstream social science in support. However, there is no reason why concept of assessment cannot elasticated to include concerns interpretive and humanities. Building on forty-...

Abstract This article examines the changes taken place over decades after a test-based accountability system was in and proposes an agenda for consequential research of testing program. The starts with review theories (Supovitz, Journal Educational Change 10:211–227, 2009) socially grounded, integrated approach to test validation (Chalhoub-Deville, Language Testing 33:453–472, 2016; Chalhoub-De...

background: malocclusion, as a worldwide issue, can cause a lot of problems for patients. panoramic (pr) and lateral cephalometric (lcr) radiographs are both usually indicated for orthodontic treatments. the aim of this study was to analyze vertical and sagittal parameters of both jaws on prs and to compare them on lcrs. materials and methods: in this cross sectional study, 61 samples from all ...

let r be a right gf-closed ring with finite left and right gorenstein global dimension. we prove that if i is an ideal of r such that r/i is a semi-simple ring, then the gorensntein flat dimensnion of r/i as a right r-module and the gorensntein injective dimensnnion of r/i as a left r-module are identical. in particular, we show that for a simple module s over a commutative gorensntein ring r, ...

It is shown that the category of non-Archimedean metric spaces with l-Lipschitz maps can be embedded as a coreflectlve non-bireflective subcategory in the category of fuzzy uniform spaces. Consequential characterizations of topological and unif’orm properties are derived.
