This test of novel problem solving is a measure of fluid intelligence (Doubleday‚ King‚ & Papageorgiou‚ 2002). People’s ability to solve novel problems is a stable characteristic‚ as it is largely genetically determined (Nairne‚ 2009). Test-retest is typically appropriate for measures with stable attributes‚ but this test’s novel nature makes it an inappropriate technique in regard to reliability. In effect‚ its novelty diminishes after the initial testing‚ producing difficulties due to practice

BA 117 Problem Set #1 - CVP Deadline: November 26‚ 2011 A. The break-even point in units can be computed as Fixed Costs divided by the contribution margin per unit. On the other hand‚ the break-even point in pesos can be computed as Fixed Costs divided by the contribution margin ratio. Using the profit equation π = TR – TC; where π = operating profit‚ TR = Total Revenue and TC = Total Cost‚ derive the break-even formulas. B. From the profit equation π = TR – TC‚ derive the formula for the

Ciliates are concentrated by centrifugation or settling and then washed two to three times with distilled water by centrifugation until the yellow colour disappears. Avoid excessive washing‚ as this may weaken the impregnation. After the last washing‚ discard supernatant‚ leaving about 0.1 ml of the sample. Add 0
