Academic nepotism – all that glitters is not gold
Dear Editor With increasing emphasis on publications forfaculty recruitment, career advancementand obtaining research grants, the issues relatedto author kinship and academic nepotism havegrown significantly and these probably reflectthe inflationary growth rather than the optimalgrowth warranted due to increasing researchcomplexity. Allesina S (1) measured the fullmagnitude of nepotism in the ...
متن کاملNot All Fair Probabilistic Schedulers Are Equivalent
We propose a novel, generic definition of probabilistic schedulers for population protocols. We then identify the consistent probabilistic schedulers, and prove that any consistent scheduler that assigns a non-zero probability to any transition i → j, where i and j are configurations satisfying i = j, is fair with probability 1. This is a new theoretical framework that aims to simplify proving ...
متن کاملAll That Glisters is Not Gold - Genes, Transgenesis and Behavior
1. Genetic background. ES cells are most commonly made from mouse strains (such as 129) that harbour a mutation or mutations, so far unknown, that permit the outgrowth and proliferation of cells from the early embryo. ES cells are reported to have been prepared from other strains, including BL/6, but these have not been widely used. There are also potential problems of strain typing that could ...
متن کاملMetabolic equivalent: one size does not fit all.
The metabolic equivalent (MET) is a widely used physiological concept that represents a simple procedure for expressing energy cost of physical activities as multiples of resting metabolic rate (RMR). The value equating 1 MET (3.5 ml O2 x kg(-1) x min(-1) or 1 kcal x kg(-1) x h(-1)) was first derived from the resting O2 consumption (VO2) of one person, a 70-kg, 40-yr-old man. Given the extensiv...
متن کاملNonlinear Autoassociation Is Not Equivalent to PCA
A common misperception within the neural network community is that even with nonlinearities in their hidden layer, autoassociators trained with backpropagation are equivalent to linear methods such as principal component analysis (PCA). Our purpose is to demonstrate that nonlinear autoassociators actually behave differently from linear methods and that they can outperform these methods when use...
