Human subjects overestimate the change of rising intensity sounds compared with falling intensity sounds. Rising sound intensity has therefore been proposed to be an intrinsic warning cue. In order to test this hypothesis, we presented rising, falling, and constant intensity sounds to healthy humans and gathered psychophysiological and behavioral responses. Brain activity was measured using eve...

We investigate non-homogeneous linear differential equations of the form x′′(t) + x′(t) − x (t) = p (t) where p (t) is either a polynomial or a factorial polynomial in t. We express the solution of these differential equations in terms of the coefficients of p (t), in the initial conditions, and in the solution of the corresponding homogeneous differential equation y′′(t) + y′(t) − y (t) = 0 wi...

Whereas public information campaigns have failed to reverse the rising trend in obesity, economists support food taxes as they suggest they can force individuals to change their eating behavior and make the agro-food industry think more about healthy food products. Excise taxes based on the unhealthy nutrient content would be more effective since they impact more on unhealthy food products than...

Many elderly people have difficulty with the common functional activity of rising from a chair. Previous work has identified different strategies that are used to assist the young, the healthy elderly, and the functionally impaired elderly subjects in this activity. For the young and the healthy elderly, modification of these strategies with decreased chair height has been examined. This study ...

In this article, improved bounds for (kn)! and the factorial polynomial are obtained using Kober’s inequality and Lagrange’s identity.

Evidence suggests that scores on various intelligence tests have been rising at a fast rate. To find out whether performance on the Wechsler Adult Intelligence Scale (WAIS) Vocabulary subtest has also been rising, the authors searched major psychology journals for investigations involving healthy younger and older adult participants and collected the reported WAIS Vocabulary scores. The meta-an...

A significant problem for the food industry is delivering high-quality, healthy in response to rising demands brought on by expanding worldwide population [...]

harkey & Sharkey (2010) have written a most interesting paper, raising interesting ethical and practical issues regarding robots as sole and parttime carers. What competencies can robots achieve in the near term? Can we experience social relatedness with them (and they with us)? Can robots care (in the sense of nurture) for us? Are their risks in deploying robots as carers for the young? Can we...
