Report On Libraries And Mobile Technologies In The Age Of The Visible College By Bryan Alexander, Mary Ellen Kenreich

Mary Ellen Kenreich

How is the mobile revolution transforming libraries? What will library services and librarians look like in the age of a ubiquitously networked civilization? We begin by surveying what changes have already hit: an expanded device universe,

the e-book renaissance, the growth of new media

ecosystems, nearly-always-on user access, and the

initial switch from 'library as place' to 'place as library'.

Next we assess how mobility has impacted academia,

from teaching to research and student life. Then we

explore scenarios of the future, based on an analysis of

current trends. Scenarios include: Post-Residential

Academe; Open World; Silo World; Alt.Residential.

Integrating Economics And System Dynamics Approaches For Modeling An Ecological-Economic System, Takuro Uehara, Yoko Nagase, Wayne W. Wakeland

Wayne W. Wakeland

This article describes collaboration between system dynamicists and economists to model a multi-sector, ecological-economic model of population and resource dynamics that is firmly based on economic theory and leverages the strengths of both fields. This model illuminates how an SD approach allows model complexity to be extended in order to effectively model interactions between an economic system and an ecological system. Specifically, the simulation exercise demonstrates how SD model analysis can help explain the counterintuitive model behaviors due to increases in the natural resource carrying capacity or regeneration rate. The simulation results also reveal that allowing for out-of-equilibrium states (adaptation) …
