The topic of data sharing contributes prominently to the current zeitgeist in cognitive neuroimaging. This issue of Journal of Cognitive Neuroscience, for instance, follows closely on the heels of 5 articles on the topic that appeared back-to-back in Nature Reviews Neuroscience (Bjaalie, 2002; Fox & Lancaster, 2002; Koslow, 2002; Toga, 2002; Van Horn & Gazzaniga, 2002). What we offer in this co...

According to Gabriel Marcel, being cannot be approached directly through a conceptual way, because it belongs to the real territory of mystery rather than that of problem. One of the most important concepts in Marcel’s philosophy is that of hope. Marcel’s conception of hope relies upon a distinction between “having” and “being.”  We do not have a belief; we are in a belief. Similarly, ...

Every ring R with identity satisfies the following property: the factor ideals of R (i.e., those ideals I such that I+ J= R and In J= (0) for some ideal J) form a Boolean sublattice of the lattice of all ideals of R. The universal algebraic abstraction of this property is known as Boolean factor congruences (BFC) or as the strict refinement property; more examples of algebras having BFC are lat...

Are you stressed out? Is your in box taller than you are? Do you have suicide hotline on speed dial? If you're not having fun at work, you're not alone.

25 Interpretations on the origin of sustained flight in birds are mainly driven by biomechanical 26 studies from fossil evidence and have largely neglected how the metabolic requirements of 27 flight would have been supported. We studied tinamous, a taxon of flying palaeognathous 28 birds with the smallest heart among birds to evaluate the hypothesis that heart size restricts 29 aerobic perform...

The measure of a monic polynomial is the product of the absolute value of the roots which lie outside and on the unit circle. We describe an algorithm, based on the root-squaring method of Graeffe, for finding all polynomials with integer coefficients whose measures and degrees are smaller than some previously given bounds. Using the algorithm, we find all such polynomials of degree at most 16 ...

This paper defends the Famine Relief Argument against Having Children, which goes as follows: conceiving and raising a child costs hundreds of thousands of dollars; that money would be far better spent on famine relief; therefore, conceiving and raising children is immoral. It is named after Peter Singer’s Famine Relief Argument because it might be a special case of Singer’s argument and becaus...

We show, in an effective way, that there exists a sequence of congruence classes ak (mod mk) such that the minimal solution n = nk of the congruence φ(n) ≡ ak (mod mk) exists and satisfies log nk/ logmk → ∞ as k → ∞. Here, φ(n) is the Euler function. This answers a question raised in [3]. We also show that every congruence class containing an even integer contains infinitely many values of the ...
