An update to the thermochromic cobalt(II) chloride equilibrium demonstration is described. Filter paper that has been saturated with aqueous cobalt(II) chloride is heated for seconds in a microwave oven, producing a color change. The resulting pink and blue map is used to colorfully demonstrate Le Châtelier's principle and to illuminate the…

The esterification reaction of salicylic acid with ethanol is performed in presence of dissolved 12-tungstophosphoric Brønsted-Lowry acid catalyst, a Keggin-type polyoxometalate (POM). The monitoring of the reaction with smell and the recovery of the catalyst with sight is presented. Formation of the sweet-scented ester is apparent from the smell.…

Segmental variation in maternal speech to children changes over time. This study investigated variation in non-citation speech processes in a longitudinal, 26-hour corpus of maternal northern Australian English. Recordings were naturalistic parent-child interactions when children (N = 4) were 1;6, 2;0, and 2;6. The mothers' speech was…

According to the Extended Statistical Learning account (ExSL; Stokes, Kern & dos Santos, 2012) late talkers (LTs) continue to use neighborhood density (ND) as a cue for word learning when their peers no longer use a density learning mechanism. In the current article, LTs expressive ("active") lexicon ND values differed from those of…

In the present study we investigate the production of gesture, intonation, and eye-gaze within the proto-imperative behaviour of one English child aged 1;0 to 1;7. The study is based on the qualitative and quantitative analysis of the three behaviours. The results indicate a shift from reaching gestures to points, and from rising terminal pitch…

Skinfold prediction equations recommended by the American College of Sports Medicine underestimate body fat percentage. The purpose of this research was to validate an alternative equation for men created from dual energy x-ray absorptiometry. Two hundred ninety-seven males, aged 18-65, completed a skinfold assessment and dual energy x-ray…

This study examines how three captioning types (i.e., on-screen text in the same language as the video) can assist L2 learners in the incidental acquisition of target vocabulary words and in the comprehension of L2 video. A sample of 133 Flemish undergraduate students watched three French clips twice. The control group (n = 32) watched the clips…
