The Nursing Education Exchange (NEXus) is a consortium of academic doctoral programs in nursing, initiated in response to a national shortage of well-qualified nurse educators and the need to increase the number of doctoral faculty in nursing programs across the United States. The vision for the consortium was to use distance-accessible delivery methods to provide rural nurse educators and clin...

A morphometric study of the nexus of rat cardiac muscle was carried out. The nexus surface of one intercalated disk of one 15 microm thick fiber is found to range between 47 microm(2) and 94 microm(2), the latter value taking into account the maximal underestimation caused by tangential sectioning. Dividing the lower, minimal value by the surface of the observed subunits (90 A periodicity), one...

The Nexus-PORTAL-DOORS System (NPDS) has been designed with the Hierarchically Distributed Mobile Metadata (HDMM) architectural style to provide an infrastructure system for managing both lexical and semantic metadata about both virtual and physical entities. We describe version 0.8 of NPDS, including the separation of concerns between the original Problem-Oriented Registry of Tags And Labels (...

The temporal-parietal junction (TPJ) has been proposed to support either specifically social functions or non-specific processes of cognition such as memory and attention. To account for diverse prior findings, we propose a nexus model for TPJ function: overlap of basic processes produces novel secondary functions at their convergence. We present meta-analytic evidence that is consistent with t...

The financial intermediation–growth nexus is a widely studied topic in the literature of development economics. Deepening financial intermediation may promote economic growth by mobilizing more investments, and lifting returns to financial resources, which raises productivity. Relying on provincial panel data from China, this paper attempts to examine if regional productivity growth is accounte...

Gap-junction channels, the cytoplasmic proteins that associate with them, and the transcriptional networks that regulate them are increasingly being viewed as critical communications hubs for cell signaling in health and disease. As a result, the term "nexus," which was the original structural name for these focal intercellular links, is coming back into use with new proteomic and transcriptomi...

High-speed wide-area networks enable innovative applications that integrate geographically distributed computing, database, graphics, and networking resources. The Message Passing Interface (MPI) can be used as a portable, high-performance programming model for such systems. However, the wide-area environment introduces challenging problems for the MPI implementor, because of the heterogeneity ...

The world of spatial data is split into individual data source islands that have different thematic or spatial focuses. When attempting to integrate those data sources, severe challenges arise, since for most GIS application domains a spatial integration schema does not exist. This is also true for the newly emerging domain of mobile, context-aware applications. Since the users of these systems...
