Sequential effects are not trivial context effects in psychophysical research

39 Psychophysical judgements depend on prior events. When the response to the stimulus is affected by both, stimuli presented and responses obtained on previous trials, we speak of sequential effects. Although many psychology textbooks point out to the importance of sequential effects, most of the studies simply neglect them. In Lockhead’s (1992) words, a common assumption in psychophysical sca...

What are maternal effects (and what are they not)?

Maternal effects can play an important role in a diversity of ecological and evolutionary processes such as population dynamics, phenotypic plasticity, niche construction, life-history evolution and the evolutionary response to selection. However, although maternal effects were defined by quantitative geneticists well over half a century ago, there remains some confusion over exactly what pheno...

The p - cones in dimension n ≥ 3 are not homogeneous when p 6 = 2

Using the T -algebra machinery we show that the only strictly convex homogeneous cones in R with n ≥ 3 are the 2-cones, also known as Lorentz cones or second order cones. In particular, this shows that the p-cones are not homogeneous when p 6= 2, 1 < p <∞ and n ≥ 3, thus answering a problem proposed by Gowda and Trott.

Effects of Various Rates and Concentrations of N-P-K on Growth ‘Rio Grande’ Tomato Seedling

Tomato  (L.ycopersicon esculentum  Mill.) cv. Rio Grande  seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week   N(60% NO3+40% NH4)-P-K (20-20-20) and later two week  N(30%NO3+70% NH4)-P-K...
