This qualitative study explores the subjective experience of being led by investigating the impact of their Implicit Leadership Theories (ILTs) on followers’ cognitive processes, affective responses and behavioural intentions towards leadership-claimants. The study explores how such responses influence the quality of hierarchical work-place relationships using a framework based on Leader-Member Exchange (LMX) Theory. The research uses focus groups to elicit descriptions of ILTs held by forty final year undergraduate Business and Management students. The data was then analysed using an abductive process permitting an interpretative understanding of the meanings participants attach to their past experiences and future expectations. This research addresses a perceived gap by making a theoretical contribution to knowledge and understanding in this field, focusing on how emotional responses affect their behaviour, how this impacts on organisational outcomes, and what the implications are for HRD practitioners. The findings support previous research into the content and structure of ILTs but extend these by examining the impact of affect on workplace behaviour. Findings demonstrate that where follower ILT needs are met then positive outcomes ensued for participants, their superiors, and their organisations. Conversely, where follower ILT needs are not matched, various negative effects emerged ranging from poor performance and impaired well-being, to withdrawal behaviour and outright rebellion. The research findings suggest dynamic reciprocal links amongst outcomes, behaviours, and LMX, and demonstrate an alignment of cognitive, emotional and behavioural responses that correspond to either high-LMX or low-LMX relationships, with major impacts on job satisfaction, commitment and well-being.

This paper reviews the construction of quantum field theory on a 4-dimensional spacetime by combinatorial methods, and discusses the recent developments in the direction of a combinatorial construction of quantum gravity.

We consider SU(3)-equivariant dimensional reduction of Yang Mills theory over certain cyclic orbifolds of the 5-sphere which are Sasaki-Einstein manifolds. We obtain new quiver gauge theories extending those induced via reduction over the leaf spaces of the characteristic foliation of the Sasaki-Einstein structure, which are projective planes. We describe the Higgs branches of these quiver gauge theories as moduli spaces of spherically symmetric instantons which are SU(3)-equivariant solutions to the Hermitian Yang-Mills equations on the associated Calabi-Yau cones, and further compare them to moduli spaces of translationally-invariant instantons on the cones. We provide an explicit unified construction of these moduli spaces as Kahler quotients and show that they have the same cyclic orbifold singularities as the cones over the lens 5-spaces.

A set of observables is described for the topological quantum field theory which describes quantum gravity in three space-time dimensions with positive signature and positive cosmological constant. The simplest examples measure the distances between points, giving spectra and probabilities which have a geometrical interpretation. The observables are related to the evaluation of relativistic spin networks by a Fourier transform.
