The triple task technique for studying writing processes : on which task is attention focused ?
The triple task technique measures the time and cognitive effort devoted to specific writing processes by combining directed retrospection with secondary task reaction time (RT). Writing a text is the primary task and rapidly detecting auditory probes to index cognitive effort is the secondary task. The third task is retrospecting and categorizing the contents of working memory at the time of each probe. The present paper reviews studies on the reactivity and validity of the technique. Further, one recent criticism of the method's validity is tested here: namely, that the primary task for the experimenter is not the primary task for the writer, thus distorting the time and effort measurements. We found that time and effort allocated to planning, translating, executing, evaluating, and revising was the same when the writer was encouraged by instructions to focus either on the speed of responding or the accuracy of retrospection instead of the text itself. Because writing requires sustained thought and attention to produce a cumulative product, it is apparently difficult to make text production anything but the primary task. The triple task technique offers a useful alternative to pause analysis and verbal protocols for investigating the functional features of writing

Development of Replacement Heifers using Combinations of Three Forage Types and Feed Supplements (with or without Broiler Litter)
The proper management of replacement heifers is an essential component of successful cow/calf operations. The level of management and nutrition applied to replacement heifers as calves and yearlings can impact their subsequent reproductive performance and productivity
Bark-Tissue Thickness of Coastal Western Hemlock in British Columbia
Bark-tissue thicknesses of coastal western hemlock are reported. Variation in these characteristics is considered between sites, trees, and height positions. Total bark thickness did not vary significantly with site, averaging 7.4 mm, 12.2 mm, and 12.6 mm for the top, middle, and butt height positions, respectively. However, the relative contribution of the individual tissues to the total thickness did vary with site. The thickness of all bark characteristics varied with height, being least at the top position, but differing very little between middle and butt positions
