GIS managers traditionally consider three perspectives of the nature of GIS when introducing GIS into an organization. When the GIS is developed to address focused and well de® ned problems of the organization, these perspectives adequately describe the changing identities of GIS in the study of its di€ usion. However when the GIS is developed to address strategic, but vaguely de® ned problems,...

The need for global access and decentralized management of geographic information is pushing the GIS community to establish an open GIS architecture and provide distributed geographic information services. From an operational perspective, the role of client/server components underlie specification of task-oriented programming, and the modularization of GIS software. Exchange of geographic infor...

The GIS literature abounds with strategies to guide the development of a corporate GIS as a single project but lacks discussion on the long term management of the GIS. This paper documents a recent study into GIS development in a state department over an 18-year period. It applies the productional perspective of GIS to model long term GIS development diagrammatically and identiŽ es Ž ve pattern...

Nine species of the family Diastylidae, two species of the family Bodotriidae and one species of the family Pseudocumatidae are present in the Diva II and Ifremer collections. Two new species were recognized and described herein. However, one of the new species has to remain in open nomenclature due to its young developmental stage. The new species are Makrokylindrus (Makrokylindrus) abyssalis,...

In this paper, we study the nonlinear parabolic problem with p(x)growth conditions in the space W L(Q), and give a regularity theorem of weak solutions for the following equation ∂u ∂t + A(u) = 0 where A(u) = −diva(x, t, u,∇u) + a0(x, t, u,∇u), a(x, t, u,∇u) and a0(x, t, u,∇u) satisfy p(x)-growth conditions with respect to u and ∇u.

We consider the Riesz transforms ∇L−1/2, where L ≡ −divA(x)∇, and A is an accretive, n× n matrix with bounded measurable complex entries, defined on Rn. We establish boundedness of these operators on Lp(Rn), for the range pn < p ≤ 2, where pn = 2n/(n + 2), n ≥ 2, and we obtain a weak-type estimate at the endpoint pn. The case p = 2 was already known: it is equivalent to the solution of the squa...

A method for improving the fault-tolerance of cache coherent multiprocessors is proposed. By dynamically verifying coherence operations in hardware, errors caused by manufacturing faults, soft errors, and design mistakes can be detected. Analogous to the DIVA concept for singleprocessor systems, a simple version of the protocol functions as a checker for the aggressive implementation. An exampl...

Recent neural models are capable of generating quantitative patterns of speech articulation and speech acoustics. Five models are discussed here: the DIVA model, the task dynamics model, the ACT model, the Warlaumont model and the Hickok model. These models have a more or less strong background in neuroscience. Directions are identified in this paper for a further development of quantitative pr...

This article examines the significance of Diva Starz, a new line of interactive dolls aimed at young girls between 6 and 11 years for current models of literacy. It argues that these dolls have much to tell us about the construction of children as consumers, our views about ‘childhood’, and the models of literacy instruction most appropriate for giving children the skills and knowledge needed t...
