Teaching Normal Birth, Normally [PDF]
Journal of Perinatal Education, 2009 Teaching normal-birth Lamaze classes normally involves considering the qualities that make birth normal and structuring classes to embrace those qualities. In this column, teaching strategies are suggested for classes that unfold naturally, free from unnecessary interventions.

Review of Economics and Statistics, 2008 We examine Becker's (1960) contention that children are "normal." For the cross section of non-Hispanic white married couples in the U.S., we show that when we restrict comparisons to similarly-educated women living in similarly-expensive locations, completed fertility is positively correlated with the husband's income.

Normalizers of system normalizers [PDF]
Transactions of the American Mathematical Society, 1964 1. The normalizers of the system normalizers are subgroups of some importance in the theory of solvable groups initiated by P. Hall [1-5]. For example, P. Hall observed [4] that a system normalizer was contained in the hypercenter of its norm lizer. R.

The group of endotrivial modules for the symmetric and alternating groups. [PDF]
, 2010 We complete a classification of the groups of endotrivial modules for the modular group algebras of symmetric groups and alternating groups. We show that, for n ≥ p2, the torsion subgroup of the group of endotrivial modules for the symmetric groups is ...

Galois Theory for Finite Algebras of Operations and Multioperations of Rank 2
Известия Иркутского государственного университета: Серия "Математика", 2019 The construction of Galois theory for the algebras of operations and relations is a popular topic for investigation. It finds numerous applications in both algebra and discrete mathematics – especially for the perfect Galois connection, since if such a ...

Omni-Lie 2-algebras and their Dirac structures [PDF]
, 2011 We introduce the notion of omni-Lie 2-algebra, which is a categorification of Weinstein's omni-Lie algebras. We prove that there is a one-to-one correspondence between strict Lie 2-algebra structures on 2-sub-vector spaces of a 2-vector space $\V$ and ...

Normalizer property of finite groups with almost simple subgroups
Electronic Research Archive, 2022 In this paper, we prove that all Coleman automorphisms of extension of an almost simple group by an abelian group or a simple group are inner. Using our methods we also show that the Coleman automorphisms of 2-power order of an odd order group by an ...

The normalizer problem for finite groups having normal $ 2 $-complements
Electronic Research ArchiveAssume that $ H $ is a finite group that has a normal $ 2 $-complement. Under some conditions, it is proven that the normalizer property holds for $ H $.

On Fitting groups whose proper subgroups are solvable [PDF]
International Journal of Group Theory, 2016 This work is a continuation of [A. O. Asar, On infinitely generated groups whose proper subgroups are solvable, {em J. Algebra}, {bf 399} (2014) 870-886.], where it was shown that a perfect infinitely generated group whose proper ...

On the derived Lusztig correspondence
Forum of Mathematics, Sigma, 2023 Let G be a connected reductive group, T a maximal torus of G, N the normalizer of T and $W=N/T$ the Weyl group of G. Let ${\mathfrak {g}}$ and ${\mathfrak {t}}$ be the Lie algebras of G and T. The affine variety $\mathfrak {car}={
