Fluency in reading—Thirty-five years later

Paul Nation’s talents and interests extend well beyond vocabulary to include research on speaking, writing, classroom learning and teaching, reading, and fluency. In keeping with Nation’s interests in fluency, extensive reading, and reading instruction, I outline current perspectives on reading fluency and its role as a key component of reading comprehension abilities. This discussion will incl...

Password Security-- Thirty-Five Years Later

User passwords were first introduced to allow time sharing on large mainframes. Mainframes at the time were large systems within a controlled environment. Passwords were stored in plain text file with no perceived need to secure user passwords. The first documented password breach occurred when a user wanted to gain additional time on a mainframe than the allotted four hours limit. The user sim...

Thirty years later

Elliptical galaxies are modelled as homeoidally striated Jacobi ellipsoids (Caimmi & Marmo 2005) where the peculiar velocity distribution is anisotropic, or equivalently as their adjoints configurations i.e. classical Jacobi ellipsoids of equal mass and axes, in real or imaginary rotation (Caimmi 2006). Reasons for the coincidence of bifurcation points from axisymmetric to triaxial configuratio...

Tarski’s Claim (TC = Theorem 8 in [13]) follows from simple considerations in (type-free) lambda-calculus. The present note records essentially a proof of Lemma 1.1 in [16], i.e. TCL = the type-free lambdacalculus variant of TC, as well as a few historical comments appearing there. Additional remarks are meant to insure the fact that TCL can be transferred verbatim to typed lambda-calculus [TCL...
