Constructivism and the deployment of information technology into
higher education classrooms are each widely discussed in academic
literature, but generally without a critical perspective on their
interaction from a pedagogical point of view as new technology is
continuously unveiled. Information Technology and Constructivism in
Higher Education: Progressive Learning Frameworks explores the
theoretical frameworks underlying constructivist thinking and the
digital revolution in education as they impact each other. Drawing
upon a wide range of international field experts, this book
assesses the claims made for the educational effectiveness and
constructivist orientation of various technologies and
technological systems on the basis of on-the-ground applications
and implementations.
This text brings together a number of research studies, all of
which examine the behaviour of foreign exchange rates. The main
focus of the collection is on empirical characterization of
high-frequency exchange rate data. The pioneering studies
demonstrate and explain, amongst other things, the regular patterns
in intra-day foreign exchange rate activity, the effects of
macroeconomic news of rates and analyze the profitability of
technical trading rules in these markets. The collection should be
of use to students, academics and practitioners who are interested
in exchange rate dynamics.
An examination of the symbiotic and productive relationship between
fully nonlinear partial differential equations and generalized
potential theories In recent years, there has evolved a symbiotic
and productive relationship between fully nonlinear partial
differential equations and generalized potential theories. This
book examines important aspects of this story. One main purpose is
to prove comparison principles for nonlinear potential theories in
Euclidian spaces straightforwardly from duality and monotonicity
under the weakest possible notion of ellipticity. The book also
shows how to deduce comparison principles for nonlinear
differential operators, by marrying these two points of view, under
the correspondence principle. The authors explain that comparison
principles are fundamental in both contexts, since they imply
uniqueness for the Dirichlet problem. When combined with
appropriate boundary geometries, yielding suitable barrier
functions, they also give existence by Perron’s method. There are
many opportunities for cross-fertilization and synergy. In
potential theory, one is given a constraint set of 2-jets that
determines its subharmonic functions. The constraint set also
determines a family of compatible differential operators. Because
there are many such operators, potential theory strengthens and
simplifies the operator theory. Conversely, the set of operators
associated with the constraint can influence the potential theory.
This book covers research completed between 1981 and May 1985 and
includes: reviews of recent studies, sitings and investigations at
spills-of-opportunity as well as results of recent arctic and
sub-Arctic oil weathering experiments and observations on the
behavior of crude oil in the presence of ice. Topics covered
include the following: laboratory studies of formation and
stability of water-in-oil emulsions; selected case histories of the
more detailed chemistry studies of mousse behavior and long term
fate in near-coastal and open ocean oil spills/blowouts; tar ball
formation and distribution; and algorithms and computer programs to
simulate the formation of water-in-oil emulsion.

This book constitutes the refereed proceedings of the 10th
International Workshop on Cooperative Information Agents, CIA 2006,
held in Edinburgh, UK in September 2006. The 29 revised full papers
presented together with four invited papers were carefully reviewed
and selected from 58 submissions. The papers are organized in
topical sections.
