Although experimental studies have shown a strong impact of text layout on the legibility of etext, many digital texts appearing in eBook or the internet use different designs, so that there is no straightforward answer in the literature over which one to follow when designing ematerial. Therefore, in this paper we shall focus on the text layout, particularly the influence of line length on rea...

OBJECTIVE We report (1) the quantitative investigation of text reading in posterior cortical atrophy (PCA), and (2) the effects of 2 novel software-based reading aids that result in dramatic improvements in the reading ability of patients with PCA. METHODS Reading performance, eye movements, and fixations were assessed in patients with PCA and typical Alzheimer disease and in healthy controls...

In this paper we will determine the multiple point manifolds of certain self-transverse immersions in Euclidean spaces. Following the triple points, these immersions have a double point self-intersection set which is the image of an immersion of a smooth 5-dimensional manifold, cobordant to Dold manifold $V^5$ or a boundary. We will show there is an immersion of $S^7times P^2$ in $mathbb{R}^{1...

We use a regression-discontinuity design to study the effects of double blocking sixth-grade students in reading and mathematics on their achievement across three years of middle school. To identify the effect of the intervention, we use sharp cutoffs in the test scores used to assign students to double blocking. We find large, positive, and persistent effects of double blocking in reading, but...
