The Naturality of Natural Deduction [PDF]
Studia Logica, 2017 Developing a suggestion by Russell, Prawitz showed how the usual natural deduction inference rules for disjunction, conjunction and absurdity can be derived using those for implication and the second order quantifier in propositional intuitionistic second order logic $NI^2$.

Nature Natured and Nature Denatured [PDF]
Hastings Center Report, 2014 AbstractThose who want to observe, analyze, and make judgments about synthetic biology need to think about where to stand in the world so as to get an informed sense of which new capacities and incapacities are actual and which matter. They will need something like “upstream ethics”—but not because they want to “get ahead” of the imagined onslaught of ...

Naturally Full Functors in Nature [PDF]
Acta Mathematica Sinica, English Series, 2005 We introduce and discuss the notion of naturally full functor. The definition is similar to the definition of separable functor: a naturally full functor is a functorial version of a full functor, while a separable functor is a functorial version of a faithful functor. We study general properties of naturally full functors.

The Nature of Nature as a Stakeholder [PDF]

Likewise, there have been discussions on whether nature should be considered a stakeholder of the firm. However, one seldom encounters any definitions of the key concepts, that is of nature or the natural environment.

A Natural Series for the Natural Logarithm [PDF]
The Electronic Journal of Combinatorics, 2008 Rodriguez Villegas expressed the Mahler measure of a polynomial in terms of an infinite series. Lück's combinatorial $L^2$-torsion leads to similar series expressions for the Gromov norm of a knot complement. In this note we show that those formulae yield interesting power series expansions for the logarithm function.

A Natural Love of Natural Products [PDF]
The Journal of Organic Chemistry, 2008 Recent research on the chemistry of natural products from the author's group that led to the receipt of the ACS Ernest Guenther Award in the Chemistry of Natural Products is reviewed. REDOR NMR and synthetic studies established the T-taxol conformation as the bioactive tubulin-binding conformation, and these results were confirmed by the synthesis of ...

On the Nature of Natural Selection
, 2018 Some philosophers, known as statisticalists, claim that the concept of natural selection, as it is normally presented in population genetics, is statistical in character and cannot be construed in causal terms. On the contrary, other philosophers, known as causalists, argue against the statistical view and reaffirm the causal interpretation of natural ...
