TL;DR: In this paper, the authors discuss the development and testing of snow algorithms with specific reference to their use and application in land surface models and make recommendations with respect to: (a) density of new and aged snow in open and forest environments; (b) interception of snow by evergreen canopies; (c) redistribution and sublimation of snow water equivalent by blowing snow; (d) depletion in snow-covered area during snowmelt; (e) albedo decay during melting; (f) turbulent transfer during snow melt; and (g)
Abstract: This paper discusses the development and testing of snow algorithms with specific reference to their use and application in land surface models. New algorithms, developed by the authors, for estimating snow interception in forest canopies, blowing snow transport and sublimation, snow cover depletion and open environment snowmelt are compared with field measurements. Existing algorithms are discussed and compared with field observations. Recommendations are made with respect to: (a) density of new and aged snow in open and forest environments; (b) interception of snow by evergreen canopies; (c) redistribution and sublimation of snow water equivalent by blowing snow; (d) depletion in snow-covered area during snowmelt; (e) albedo decay during snowmelt; (f) turbulent transfer during snowmelt; and (g) soil heat flux during meltwater infiltration into frozen soils. Preliminary evidence is presented, suggesting that one relatively advanced land surface model, CLASS, significantly underestimates the timing of snowmelt and snowmelt rates in open environments despite overestimating radiation and turbulent contributions to melt. The cause(s) may be due to overestimation of ground heat loss and other factors. It is recommended that further studies of snow energetics and soil heat transfer in frozen soils be undertaken to provide improvements for land surface models such as CLASS, with particular attention paid to establishing the reliability of the models in invoking closure of the energy equation. #1998 John Wiley & Sons, Ltd.

TL;DR: This case illustrates some means of increasing the utility of forced-choice malingering tests, as a 45-year-old restaurant owner claimed that he was unable to work because of impaired memory for seven years following head trauma.
Abstract: For seven years following head trauma, a 45-year-old restaurant owner had claimed that he was unable to work because of impaired memory. A specially designed forced-choice memory test yielded performance significantly below the chance level and thus indicated malingering. This case illustrates some means of increasing the utility of forced-choice malingering tests.

10 Apr 2010TL;DR: It is found that people's accuracy in describing the embellished charts was no worse than for plain charts, and that their recall after a two-to-three-week gap was significantly better, questioning some of the premises of the minimalist approach to chart design.
Abstract: Guidelines for designing information charts (such as bar charts) often state that the presentation should reduce or remove 'chart junk' - visual embellishments that are not essential to understanding the data. In contrast, some popular chart designers wrap the presented data in detailed and elaborate imagery, raising the questions of whether this imagery is really as detrimental to understanding as has been proposed, and whether the visual embellishment may have other benefits. To investigate these issues, we conducted an experiment that compared embellished charts with plain ones, and measured both interpretation accuracy and long-term recall. We found that people's accuracy in describing the embellished charts was no worse than for plain charts, and that their recall after a two-to-three-week gap was significantly better. Although we are cautious about recommending that all charts be produced in this style, our results question some of the premises of the minimalist approach to chart design.

TL;DR: In this paper, the authors proposed a new approach that improves upon current methods of flat surface treatment, based on the recognition that in natural landscapes drainage is generally away from higher and towards lower terrain, to produce a drainage pattern over the flat surface that is topographically consistent and exhibits flow convergence properties.
