Social Policy &Administration, EarlyView.ABSTRACT Young people not in employment, education, or training (NEET) often face complex and overlapping challenges, yet the welfare services intended to support them are fragmented across organisational boundaries. This article contributes to the literature by exploring how street‐level bureaucrats in a Swedish municipality understand and navigate ...

Exact sequences for relative Brauer groups and Picard groups [PDF]
, 1983 Relative Brauer groups and Picard groups have been introduced in [19] resp. [17]. In both papers we restricted atteention to the Brauer group resp. Picard group of a single couple (R,σ) consisting of a commutative ring R and an indempotent kernel funktor

Psychotropic medication and the fetal brain
The Journal of Physiology, EarlyView.Abstract figure legend Brain region changes linked to in‐utero psychotropic exposure. Abstract Medications known to cross the blood–brain barrier (psychotropic medications) are commonly prescribed to women during pregnancy, often for the management of mental illness.

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

Brauer relations in finite groups [PDF]
, 2015 If GG is a non-cyclic finite group, non-isomorphic GG-sets X,YX,Y may give rise to isomorphic permutation representations C[X]≅C[Y]C[X]≅C[Y]. Equivalently, the map from the Burnside ring to the rational representation ring of GG has a kernel.

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.ABSTRACT The structure of stream networks naturally fragments freshwater habitats, but this complexity is increasingly intensified by dams and reservoirs. How anthropogenic fragmentation interacts with natural isolation gradients to affect fish populations remains poorly understood.

Minimal and random generation of permutation and matrix groups [PDF]
, 2012 We prove explicit bounds on the numbers of elements needed to generate various types of finite permutation groups and finite completely reducible matrix groups, and present examples to show that they are sharp in all cases.

Abelian number fields with frobenian conditions
Mathematika, Volume 72, Issue 4, October 2026.Abstract We study the distribution of abelian number fields with frobenian conditions imposed on the conductor. In particular, we find an asymptotic for the number of abelian field extensions of a number field k$k$ whose conductor is the sum of two squares. We also discuss an application of the Brauer group of stacks to quadratic number fields.

Some isomorphisms for the Brauer groups of a Hopf algebra
, 2001 Using equivalences of categories we provide general isomorphisms between the Brauer groups of different Hopf algebras. One of those is used to prove that the Brauer groups BC(k, H_4, r(1)) for every dual quasitriangular structure r(t) on Sweedler's Hopf ...

The Brauer trees of non-crystallographic groups of Lie type [PDF]
, 2014 In this article we determine the Brauer trees of the unipotent blocks with cyclic defect group in the ‘groups’ I2(n,q), H3(q) and H4(q). The degrees of the unipotent characters of these objects were given by Lusztig, and using the general theory of ...
