EXPRESS: On the Emotional Dynamics of Guided Strategizing: An Affective View on Strategy-Making directed by Strategy Consultants

While work on affect in strategy-making has been increasingly developing, relatively little research has been conducted on the emotional dynamics of strategy processes directed by strategy consultants. Drawing on a variety of qualitative data gathered during a one-year consulting case, this article looks into the way emotions unfold when managers solicit external strategic advice. Specifically, this article reveals the mechanisms underpinning managers’ emotions in guided strategy-making from pre- to post-strategizing, highlighting processes as they develop over time. In doing so, three fundamental emotional drivers are laid bare: interaction – or how practitioners engage with each other; temporality – or how practitioners engage with time; and impression – or how practitioners engage with mental representations of strategy-making and strategy consultancy. By revealing how emotions evolve when managers find themselves strategically directed, this article offers insight into how a guided strategy-making trajectory can be affectively managed – to make sense of emotions when they unfold, and to address them appropriately as they do.

SUPERCONDUCTIVITY IN THE 2D ATTRACTIVE HUBBARD MODEL WITHIN A FUNCTIONAL FIELD-THEORETICAL RG

We apply the functional field-theoretical renormalization group methodology up to two-loop order to the 2D attractive Hubbard model for weak bare interaction. Since the momentum-resolved quasiparticle weight ZΛ(p) is always close to unity in the RG flow, higher-order quantum fluctuations do not affect crucially the low-energy dynamics in this case. As a result, we observe a s-wave singlet superconducting quasi-long-range order phase as a function of doping in good agreement with other numerical methods. To assess the role played by the fluctuations we compare the critical temperature Tc in which the quasi-long-range superconducting order phase takes place within our approach with mean-field theory and quantum Monte Carlo results.

TENSOR OPTIMIZED SHELL MODEL USING BARE INTERACTION FOR LIGHT NUCLEI

We propose a new method to describe nuclear structure using bare nuclear interaction, in which the tensor and short-range correlations are described by using the tensor optimized shell model (TOSM) and the unitary correlation operator method (UCOM), respectively.

Electron-Phonon Interaction in Strongly Correlated Systems

The Hubbard-Holstein model is a simple model including both electron-phonon interaction and electron-electron correlations. We review a body of theoretical work investigating, the effects of strong correlations on the electron-phonon interaction. We focus on the regime, relevant to high-Tcsuperconductors, in which the electron correlations are dominant. We find that electron-phonon interaction can still have important signatures, even if many anomalies appear, and the overall effect is far from conventional. In particular in the paramagnetic phase the effects of phonons are much reduced in the low-energy properties, while the high-energy physics can still be affected by phonons. Moreover, the electron-phonon interaction can give rise to important effects, like phase separation and charge-ordering, and it assumes a predominance of forward scattering even if the bare interaction is assumed to be local (momentum independent). Antiferromagnetic correlations reduce the screening effects due to electron-electron interactions and revive the electron-phonon effects.
