The NGSS are meant to guide (USA) K-12 science and engineering learning and are almost always presented using text and tables. Their connectivity, however, lends them well for network modeling and interactive network visualization.

large organizations that face regulatory pressure and a need for large-scale coordination
but may be less appropriate for smaller organizations. Core IT governance principles
embedded in the structure of CobiT, ITIL, and ISO2000 can be expressed as a set of IT
governance norms including business alignment, a risk/control perspective, systematic
measurement, accountability, and continuous improvement. In this study, we model IT
effectiveness and willingness to comply with best practices as effects of adopting these
norms. We propose a set of survey items tailored to help assess the constructs in this
model then partially validate them using principal components analysis. Survey
responses (n=86) reveal a significant connection between evidence of norm adoption in
organizations and IT success. This norms-based paradigm may be useful in bringing
some of the benefits of IT governance to the smaller organizations that are thought to
drive economic growth and employment.}, keywords = {Accounting, BIS}, author = {Marshall,Byron and Curry,Michael and Reitsma,Reindert} } @article {1974511, title = {Information Space Partitioning Using Adaptive Voronoi Diagrams}, journal = {Information Visualization}, volume = {6}, year = {2007}, month = {2007}, pages = {123-138}, abstract = {In this paper we present and evaluate a Voronoi method for partitioning continuous information spaces. We define the formal characteristics of the problem and discuss several well-known partitioning methods and approaches. We submit that although they all partially solve the problem, they all have shortcomings. As an alternative, we offer an approach based on an adaptive version of the multiplicatively weighted Voronoi diagram. The diagram is {\textquoteleft}adaptive{\textquoteright} because it is computed backwards; i.e., the generators{\textquoteright} weights are treated as dependent rather than independent variables. We successfully test this adaptive solution using both ideal-typical (artificial) and empirical data. Since the resultant visualizations are meant to be used by human subjects, we then discuss the results of a usability experiment, positioning the adaptive solution against a commonly used rectangular solution and the classic nonweighted Voronoi solution. The results indicate that in terms of usability, both the rectangular and the adaptive Voronoi solution outperform the standard Voronoi solution. In addition, although subjects are better able to gage rectangular area relationships, only the adaptive Voronoi solution satisfies all geometric constraints of weight-proportional partitioning.}, keywords = {BIS}, author = {Reitsma,Reindert and Trubin,Stanislav} }
