Re-balancing the excellence frameworks with individualistic logic

The analysis and assessment of business excellence are often associated with the discussion on the design and justification of the excellence measures and their dimensions. This paper re-visits the critical issues in assessing business excellence, and aims to explore the conceptual development on re-balancing the performance dimensions in view of a framework. Based on the synthesising of published literatures and case studies it reveals that all the published excellence frameworks are based on the commonality logic ; and it suggests re-balancing them with the individualistic logic . This concept has then been operationalised by constructing a new excellence framework named world-class diamond model. Based on the surveyed data and by using structural equation modelling the re-balanced diamond model is tested and analysed in order to secure its theoretical validity. With the re-balanced framework, it stresses the critical importance of the individualistic logic in achieving business excellence. It also argues that the managerial implication of the individualistic logic lies in the firm-specific and situation-sensitive practices of business excellence. The original contribution of the research is a conceptually re-balanced perspective of business excellence, suggesting a shift from commonality logic towards individualistic logic

SU(2)-Colored (A)dS Black Holes in Conformal Gravity

We consider four-dimensional conformal gravity coupled to the U(1) Maxwell and SU(2) Yang-Mills fields. We study the structure of general black hole solutions carrying five independent parameters: the mass, the electric U(1) and magnetic SU(2) charges, the massive spin-2 charge and the thermodynamical pressure associated with the cosmological constant, which is an integration constant in conformal gravity. We derive the thermodynamical first law of the black holes. We obtain some exact solutions including an extremal black hole with vanishing mass and entropy, but with non-trivial SU(2) Yang-Mills charges. We derive the remainder of the first law for this special solution. We also reexamine the colored black holes and derive their first law in Einstein-Yang-Mills gravity with or without a cosmological constant.Comment: Latex, 22 pages, typos corrected and references adde

Charged Black Holes in Colored Lifshitz Spacetimes

We consider Einstein gravities coupled to a cosmological constant and $SU(2)$ Yang-Mills fields in four and five dimensions. We find that the theories admit colored Lifshitz solutions with dynamic exponents $z>1$. We study the wave equations of the $SU(2)$ scalar triplet in the bulk, and find that the vacuum color modifies the scaling dimensions of the dual operators. We also introduce a Maxwell field and construct exact solutions of electrically-charged black holes that asymptote to the $D=4$, $z=3$ and $D=5$, $z=4$ colored Lifshitz spacetimes. We derive the thermodynamical first law for general colored and charged Lifshitz black holes.Comment: Latex, 13 pages, minor corrections and references adde

Electrically-Charged Lifshitz Spacetimes, and Hyperscaling Violations

Electrically-charged Lifshitz spacetimes are hard to come by. In this paper, we construct a class of such solutions in five dimensional Einstein gravity coupled to Maxwell and $SU(2)$ Yang-Mills fields. The solutions are electrically-charged under the Maxwell field, whose equation is sourced by the Yang-Mills instanton(-like) configuration living in the hyperbolic four-space of the Lifshitz spacetime. We then introduce a dilaton and construct charged and colored Lifshitz spacetimes with hyperscaling violations. We obtain a class of exact Lifshitz black holes. We also perform similar constructions in four dimensions.Comment: Latex, 14 page

Charged Black Holes with Scalar Hair

We consider a class of Einstein-Maxwell-Dilaton theories, in which the dilaton coupling to the Maxwell field is not the usual single exponential function, but one with a stationary point. The theories admit two charged black holes: one is the Reissner-Nordstr{\o}m (RN) black hole and the other has a varying dilaton. For a given charge, the new black hole in the extremal limit has the same AdS$_2\times$Sphere near-horizon geometry as the RN black hole, but it carries larger mass. We then introduce some scalar potentials and obtain exact charged AdS black holes. We also generalize the results to black $p$-branes with scalar hair.Comment: Latex, 22 pages, typos corrected and references added, to appear in JHE
