Lights, Camera, Accessibility! Applications in Video Design
No full textThe focus of this lesson is the authentic application of accessibility for a video through an asynchronous discussion forum. Set in an online, graduate, education multimedia design course, students design an instructional video over multiple weeks, applying course content to their video, demonstrating their application, and receiving formative feedback through discussion forums. This article details one discussion forum, occurring over one asynchronous week, used as a formative assessment to support students in applying accessibility guidelines (WCAG 2.1 and Section 508) and best practices for accessible multimedia design
On the numerical range of Kac-Sylvester matrices
No full textIn this paper, the boundary generating curves and the numerical range of Kac-Sylvester matrices up to the order are characterized. Based on the obtained results and on several computational experiments performed with the Mathematica and MatLab programs, we conjecture that the found types of algebraic curves, namely ellipses and ovals, will appear for an arbitrary order
The inverse of a symmetric nonnegative matrix can be copositive
No full textLet be an symmetric matrix. We first show that if and its pseudoinverse are strictly copositive, then is positive semidefinite, which extends a similar result of Han and Mangasarian. Suppose is invertible, as well as being symmetric. We showed in an earlier paper that if is nonnegative with zero diagonal entries, then can be copositive (for instance, this happens with the Horn matrix), and when is copositive, it cannot be of form , where is positive semidefinite and is nonnegative and symmetric. Here, we show that if is nonnegative with zero diagonal entries and one positive diagonal entry, then can be of the form , and we show how to construct . We also show that if is nonnegative with one zero diagonal entry and positive diagonal entries, then cannot be copositive

Refusing the Sentimental Italian Immigration Story in Denise Giardina’s Storming Heaven
No full textThis article examines how Denise Giardina’s award-winning novel Storming Heaven offers a counterpoint to views of early twentieth-century Italian immigration to the US that rely on assimilationist conclusions. The story of Sicilian immigrant Rosa Angelelli is embedded within the fictional retelling of West Virginia labor history known as the Mine Wars. Giardina creates a female immigrant protagonist who makes plain the abuse and trauma Italian immigrant women and girls face. This point-of-view is normally obfuscated in favor of a male immigrant’s perspective, but Rosa’s story is neither ignored nor erased. As one of four protagonists in the novel, Rosa’s fractured remembrances are told through a halting discourse, revealing her isolation and the danger that awaits her no matter the choices she makes. Taking from Loretta Baldassar and Donna Gabaccia’s ideas on personal intimacy, Rosa’s struggles are not an exception, but an object lesson in how immigrant women and girls are often left with no means to develop community or intimacy, endangering their physical, mental, emotional, and spiritual well-being
