Previous methods of analyzing the substance of political attention have had to make several restrictive assumptions or been prohibitively costly when applied to large-scale political texts. Here, we describe a topic model for legislative speech, a statistical learning model that uses word choices to infer topical categories covered in a set of speeches and(More)
This paper is written as part of the European Commission’s Leonardo Da Vinci project "Mobile Learning: The Next Generation of Learning" in collaboration between three of the project partners. The paper profiles three separate research areas undertaken by the partners addressing trends and practice of integrating new media and ICT applications in education.(More)
Extreme heat events are likely to become more frequent in the coming decades owing to climate change1,2. Exposure to extreme heat depends not only on changing climate, but also on changes in the size and spatial distribution of the human population. Here we provide a new projection of population exposure to extremeheat for the continentalUnited States that(More)
PURPOSE Targeted inhibition of Müller cell (MC)-produced VEGF or broad inhibition of VEGF with an intravitreal anti-VEGF antibody reduces intravitreal neovascularization in a rat model of retinopathy of prematurity (ROP). In this study, we compared the effects of these two approaches on retinal vascular development and capillary density in the inner and(More)
This paper investigates interactions between user expertise and formats of instructional presentations. A cognitive load approach assumes that information presentation should be structured to eliminate any avoidable load on working memory. The level of learner expertise is a major factor determining intelligibility of information for a user. A diagram might(More)
In this study we investigated resting left ventricular structure and function in elite female weightlifters. Fifteen National Squad members [mean age (SD) 25 (6) years] were compared to a recreationally active control group [n = 46, 23 (3) years]. Subjects were matched for body mass, body surface area and fat free mass, but the controls were slightly taller(More)
