> DDI’s own research on HR practices indicates enormous room for improvement in the application of hiring, leadership development, and succession management initiatives. For example, in one study, more than 50 percent of the survey respondents rated their organization’s succession management system 5 or lower on a 10-point effectiveness scale (10 = highly effective). And in another study, only ...

Few fast statistical signal processing algorithms exist for large problems involving non-stationary processes and irregular measurements. A recently introduced class of multiscale autoregressive models indexed by trees admits signal processing algorithms which can efficiently deal with problems of this type. In this paper we provide a novel and efficient algorithm for translating any secondorde...

An asymptotically stable minimal order realization of a partial sequence of Markov parameters is achieved by reducing the problem to a standard but minimal one in decision algebra. Summary—In this paper two equivalent sets of necessary and sufficient conditions for the existence of an asymptotically stable partial realization are developed. Both sets are expressed as multivariable polynomial eq...

We review the construction by G. Felder and the author of the realization of the elliptic quantum groups by quantum currents. . The elliptic quantum groups were introduced by G. Felder in [14]. These are algebraic objects based on a solution R(z, λ) of the dynamical Yang-Baxter equation. Here dynamical means that in addition to the spectral parameter z, the R-matrix depends on a parameter λ, wh...

le but etait de realiser un four pour pouvoir consommer, comme combustible, les debris du coke metallurgique de la siderurgie d'isphahan. ainsi, deux fours ont ete construits; l'un pour chauggage domestigue et l'autre, permettant d'atteindre une temperature plus elevee, pour les unites industrielles

The study of Granger causality has been mainly preoccupied with time series. We will instead concentrate on continuous time processes. Many systems to which it is natural to apply tests of causality take place in continuous time. For example, this is generally the case within economy. In the first part of this paper, we give a generalization of a causality relationship “G is a cause of E within...

The treatment of argument realization is rather straightforward for a language like English, but for a language with relatively free word order, such as Dutch, it is a complex matter. It is not surprising then that the devices which are commonly used to deal with it show a high degree of computational complexity. They typically include movement, as in transformational grammar, or the dissociati...

Prototypes One of the truly powerful tools in usage-centered design is the abstract prototype [Constantine, 1998; Constantine & Lockwood, 1999]. An abstract prototype allows designers to describe the contents and overall organization of a user interface without specifying its detailed appearance or behavior; it is, thus, a model of the architecture of the user interface being designed. We and o...
