Conceptualization of business excellence model with a grand theory approach

This study aims to conceptualize business excellence model and identify its variables and indicators. The philosophical foundations of the pragmatic, humanistic theory of symbolic interactionism has been, quietly and the strategy of grand theory deal with open, axial and selective coding; whose output is a new concept. Data collection is based on documentation studies on excellence models. The ...

Proton Stability in Grand Unified Theories, in Strings and in Branes

A broad overview of the current status of proton stability in unified models of particle interactions is given which includes non supersymmetric unification, SUSY and SUGRA unified models, unification based on extra dimensions, and string-M-theory models. The extra dimensional unification includes 5D and 6D and universal extra dimensional (UED) models, and models based on warped geometry. Proto...

Dual Models of Gauge Unification in Various Dimensions

We construct a compactification of the heterotic string on an orbifold T 6/Z6 leading to the standard model spectrum plus vector–like matter. The standard model gauge group is obtained as an intersection of three SO(10) subgroups of E8. Three families of SO(10) 16-plets are localized at three equivalent fixed points. Gauge coupling unification favours existence of an intermediate GUT which can ...
