Light Screens

Blue Light of the Screen is a memoir about the author's obsession with horror and the supernatural. Blue Light of the Screen is about what it means to be afraid -- about immersion, superstition, delusion, and the things that keep us up at night. A creative-critical memoir of the author's obsession with the horror genre, Blue Light of the Screen embeds its criticism of horror within a larger personal story of growing up in a devoutly Catholic family, overcoming suicidal depression, uncovering intergenerational trauma, and encountering real and imagined ghosts. As Cronin writes, she positions herself as a protagonist who is haunted by what she watches and reads, like an antiquarian in an M.R. James ghost story whose sense of reality unravels through her study of arcane texts and cursed archives. In this way, Blue Light of the Screen tells the story of the author's conversion from skepticism to faith in the supernatural. Part memoir, part ghost story, and part critical theory, Blue Light of the Screen is not just a book about horror, but a work of horror itself.

How do you keep your kids safe in a digital world? Maybe your kids are like so many others these days-too often glued to their smartphones, social media, and streaming entertainment-and you're worried. Or maybe you're wondering how to avoid digital overload. You definitely want your kids to use devices wisely...but how do you -teach them to do that? Many parents wonder: At what age should I buy my kid a phone? How long should I allow my kid to play video games each day? How can I keep my kids safe with the screens they already have? At what age should I allow my kids on social media? What if my teen insists on having their device in their bedroom at night? Parenting Generation Screen will not only equip you to set practical screen limits for your kids but also show you how to engage in meaningful conversations with your kids so they learn to be wise in the digital world. Jonathan's expert advice draws upon more than twenty years of working with teenagers and writing about the influence of digital media as well as his experiences in raising three kids (with plenty of devices!).

The scattered, inconsistent and incomplete data in the literature have prompted a comprehensive study of the physical and optical properties of projection screens. A large sample number of front and rear projection screens was obtained, representing the industry line of January 1965. The reflected and transmitted flux distribution of each sample was measured using a small, collimated test beam of white light incident normally and at 45 degrees. A vacuum photodetector, spectrally matched to the eye, was situated on a radius arm and capable of viewing the test sample at any angle in a plane. The reflectance or transmittance of the samples was calculated using data from the measured reflected flux distribution of an easily reproduced magnesium oxide standard. Measurements were made of resolving power and physical properties, and the maximum angular viewing field of each screen was determined for a typical projection geometry and tolerable field brightness gradient.
