The emergence of group fitness

Evolution, 2022
Whether and how selection can act on collectives rather than single entities has been a tumultuous issue in evolutionary biology for decades. Despite examples of multilevel selection, a simple framework is needed that makes explicit the constraints that lead to the emergence of a "group fitness function." We use evolutionary game theory to show that ...

On the fitting length of NC-groups

Geometriae Dedicata, 1991
A finite group \(G\) is called an NC-group if, for each prime \(p\), the normalizer and the centralizer of the centre of the Sylow \(p\)-subgroups of \(G\) coincide. Soluble NC-groups with arbitrarily large Fitting length and trivial centre are constructed. Theorem 4 is central to the paper: If \(H\) is a non-identity \(\{p,q\}\)-group such that \(O_ p(

Injectors in fitting sets of finite groups

Mathematical Notes, 2015
The summary in the paper has the following text: ``A set of subgroups \(\mathcal F\) of a finite group \(G\) is referred to as a Fitting set if it is closed with respect to taking normal subgroups, products of normal \(\mathcal F\)-subgroups, and inner automorphisms of \(G\). A Fitting set \(\mathcal F\) of a group \(G\) is said to be \(\pi\)-saturated

Too Much Fit with a Group? Person-Group Fit as a Moderator of the Effect of Charismatic Leadership

Academy of Management Proceedings, 2021
Drawing on theories of substitutes and contingencies for leadership, we explore how person-group (PG) fit moderates the relationship between charismatic leadership (CL) and task performance via fol...

Person-Group Fit

Journal of Management, 2012
This article explores antecedents and outcomes of group-level person-group (PG) fit perceptions. Based on the categorization-elaboration model (CEM), the authors explain how social category (gender and age) and informational diversity (education and work experience) in work teams may elicit supplementary and complementary fit perceptions among team ...
