We construct a photometric catalogue of very faint galaxies (I < ∼ 25.5) using deep CCD images taken with the 4.2m William Herschel telescope taken of fields centred on two distant X-ray luminous clusters: 1455+22 (zcl = 0.26) and 0016+16 (zcl = 0.55). Using a non-parametric procedure developed by Kaiser & Squires (1993), we analyse the statistical image distortions in our samples to derive two...

Word recognition in spoken language is known to be a dynamic, incremental, and continuous process. As words unfold in time, listeners activate a range of potential lexical candidates, including those that share semantic (Yee & Sedivy, 2006) and phonological (Allopenna, Magnuson, & Tanenhaus, 1998) features with the target word. Among the methodological techniques used to probe real-time recogni...

As teachers adopt technology in their classrooms and develop the pedagogical models that will allow them to make use of the affordances of the technology, we are seeing improved learning outcomes and high-quality learning demonstrated. The pedagogical models that are showing the most promise come from ideas about how designers can implement the class of theories referred to as constructivism. D...

Weak gravitational lensing induces distortions on the images of background galaxies, and thus provides a direct measure of mass fluctuations in the universe. The distortion signature from large-scale structure has recently been detected by several groups for the first time, opening promising prospects for the near future. Since the distortions induced by lensing on the images of background gala...

A deficiency of potassium is frequently recognized in congestive heart failure: estimates of total exchangeable body potassium are low (Aikawa et al., 1952; Burrows et al., 1954; Moore et al., 1954; Aikawa and Fitz, 1956; Moore et al., 1956; O'Meara et al., 1957; Flear et al., 1958; Birkenfeld et al., 1958). In a series of 33 episodes of congestive heart failure in 32 patients (Flear, 1960a), v...

The modulation of isotropic turbulence by particles has been investigated using direct numerical simulation (DNS). The particular focus of the present work is on the class of dilute flows in which particle volume fractions and inter-particle collisions are negligible. Gravitational settling is also neglected and particle motion is assumed to be governed by drag with particle relaxation times ra...

How does future income uncertainty affect child labour and human capital accumulation? Using a unique panel dataset, we examine the effect of changes in climate variability on the allocation of time among child labour activities (the intensive margin) as well as participation in education and labour activities (the extensive margin). We find robust evidence that increased climate variability in...

Features provide a comprehensive global overview of extent and diversity of grasslands. Analyzes how humans shaped grasslands through millennia of use and which role they play in present-day agriculture. Quantifies the role of grasslands as biodiversity hotspots as well as the drivers threatening these. Evaluates the ecosystem services grasslands provide e.g. in terms of soil protection and car...

In 1951 William Addison began his history of the English spa by noting that the vast literature on the medical and chemical properties of mineral waters "would as effectively defy analysis as the waters themselves, apparently, invite it" .' Addison, like most later historians, chose to see the spa mainly as a phenomenon of social history, of changes in manners, morals, and amusements.2 Yet our ...
