Freeman’s argument about water not being fractionated through plant transpiration sounds quite convincing, but is contradicted by the results of Kahmen et al. 2011 (PNAS 108, 1981–1986). So to the extent it relies on this non-fractionation the model by Winnick et al. has to be seen as questionable.
I’m not much impressed by the editorial quality of Elsevier’s journal Applied Energy, and with Elsevier it’s not the only one. There are several jarring occurrences of “MW/h” in Pearre et al. interspersed with the correct “MWh”. (I grudgingly accept the American convention of two fraction bars in one term, as in “$/MW/h”, but it has to be done consistently.) Is it not time to strike Elsevier off the list of reputable publishers?
What Kemp reports about America strongly smacks of the kind of ideological cleansing practised by Lyssenko and Mao. I may be misled by unfamiliar terms, but as far as I can tell the dismissed Armitage was neither a lecturer nor assistant professor but a technician, and a good one at that. Since when do university students need cloistering, indoctrination, and being protected from whacky ideas? When the university president Read the rest of this entry »
If Shimelmitz et al. are right, then humans up until the dawn of Neanderthals and moderns had to make do without the nutritional advantage of cooking. This is the opposite of what Wrangham claims, but it would explain the last synchronous spurt of brain growth in two disjunct areas of the world.
There are two rules that psychologists, sociologists and all the other humanities will probably never grasp: 1) Correlation is not causation, 2) Any regression between the most random data will always yield a definite result with a non-zero slope. Most results shown in d’Acunto et al. depend on one or two outliers alone, and those few Read the rest of this entry »
Marsh et al. are a particularly strong example for the meaninglessness of statistical significance. While their figure 2b clearly shows a significant difference at the group level, the two groups become completely identical by just taking away two individuals from each, and the predictive value Read the rest of this entry »
Successful teachers have always scattered witty or engaging anecdotes throughout their more serious stuff. Gruber et al. now show why this is so effective.
Currently the press is full about stretching before sport being not only not beneficial but downright harmful. Read the rest of this entry »
