A Description of Mixed Group Validation
Assessment, 2013Mixed group validation (MGV) is a statistical model for estimating the diagnostic accuracy of tests. Unlike the more common approach to estimating criterion-related validity, known group validation (KGV), MGV does not require a perfect external validity criterion.

The difficulties encountered in the theory of mixed Abelian groups can become decidedly less complex, if it is possible to reduce the question to mixed groups whose torsion subgroup is ๐ซ-primary. Call such a group a p-mixed group. In ยง1 we show that the splitting problem for a mixed group is reducible to the same problem for certain associated ๐ซ-mixed ...

On commutative group algebras of mixed groups
Communications in Algebra, 1997Suppose F is a perfect field of characteristic p 0 and G is an abelian group whose torsion subgroup Gt is p-primary. If Gt is totally projective of countable length, it is shown that G is a direct factor of the group of normalized units V(G) of the group algebra F(G) and that V(G)/G is a totally projective p-group.

Group Work with 'Mixed Membership' Groups
Social Work With Groups, 1994SUMMARY The small group is a social microcosm of the wider society in which it is located. Patterns of social oppression will be repeated in social group work practice unless active steps are taken to counteract these tendencies and replace them with a culture of empowerment.

Mixed Groups of Finite Nilstufe
Canadian Mathematical Bulletin, 1987AbstractThis paper constructs a class of examples to show that for torsion-free groups H with finite nilstufe v(H) = n < โ there can be divisible torsion groups D with v(H โ D) - n + k for all k โค n + 1. This answers a question of Feigelstock. The construction is based on a proposition which bounds v(H โ D) in terms of v(H) and rank (D).

Part I of this paper appeared in [Proc. Conf., Udine/Italy 1984, CISM Courses Lect. 287, 265-278 (1984; Zbl 0566.20039)]. Sect. 4 is a classification of mixed groups which have a maximal rank tfree subgroup A such that \(\tau\) (A) is finite and \(\tau\) (A/pA)\(\leq 1\) for all primes p. Sect.
