The guide is organised by the assessment structure of the
qualification and gives students guidance on the external
assessment. Key point summaries of what candidates should know are
included to reinforce teaching. Information is presented in a
straightforward, user-friendly way. Worked examples, exam
questions, revision practice questions and 'test yourself'
diagnostic questions prepare students for the exams ahead. In
addition, the Revision Guide provides students with all the answers
to all the questions in the book. 'BTEC Award in Principles of

From hashtag activism to the flood of political memes on social
media, the landscape of political communication is being
transformed by the grassroots circulation of opinion on digital
platforms and beyond. By exploring how everyday people assist in
the promotion of political media messages to persuade their peers
and shape the public mind, Joel Penney offers a new framework for
understanding the phenomenon of viral political communication: the
citizen marketer. Like the citizen consumer, the citizen marketer
is guided by the logics of marketing practice, but, rather than
being passive, actively circulates persuasive media to advance
political interests. Such practices include using protest symbols
in social media profile pictures, strategically tweeting links to
news articles to raise awareness about select issues, sharing
politically-charged internet memes and viral videos, and displaying
mass-produced T-shirts, buttons, and bumper stickers that promote a
favored electoral candidate or cause. Citizens view their
participation in such activities not only in terms of how it may
shape or influence outcomes, but as a statement of their own
identity. As the book argues, these practices signal an important
shift in how political participation is conceptualized and
performed in advanced capitalist democratic societies, as they
casually inject political ideas into the everyday spaces and places
of popular culture. While marketing is considered a dirty word in
certain critical circles - particularly among segments of the left
that have identified neoliberal market logics and consumer
capitalist structures as a major focus of political struggle - some
of these very critics have determined that the most effective way
to push back against the forces of neoliberal capitalism is to
co-opt its own marketing and advertising techniques to spread
counter-hegemonic ideas to the public. Accordingly, this book
argues that the citizen marketer approach to political action is
much broader than any one ideological constituency or bloc. Rather,
it is a means of promoting a wide range of political ideas,
including those that are broadly critical of elite uses of
marketing in consumer capitalist societies. The book includes an
extensive historical treatment of citizen-level political promotion
in modern democratic societies, connecting contemporary digital
practices to both the 19th century tradition of mass political
spectacle as well as more informal, culturally-situated forms of
political expression that emerge from postwar countercultures. By
investigating the logics and motivations behind the citizen
marketer approach, as well as how it has developed in response to
key social, cultural, and technological changes, Penney charts the
evolution of activism in an age of mediatized politics, promotional
culture, and viral circulation.
"More than anything else technology creates our world. It creates
our wealth, our economy, our very way of being," says W. Brian
Arthur. Yet despite technology's irrefutable importance in our
daily lives, until now its major questions have gone unanswered.
Where do new technologies come from? What constitutes innovation,
and how is it achieved? Does technology, like biological life,
evolve? In this groundbreaking work, pioneering technology thinker
and economist W. Brian Arthur answers these questions and more,
setting forth a boldly original way of thinking about technology.
"The Nature of Technology "is an elegant and powerful theory of
technology's origins and evolution. Achieving for the development
of technology what Thomas Kuhn's "The Structure of Scientific
Revolutions "did for scientific progress, Arthur explains how
transformative new technologies arise and how innovation really
works. Drawing on a wealth of examples, from historical inventions
to the high-tech wonders of today, Arthur takes us on a
mind-opening journey that will change the way we think about
technology and how it structures our lives. "The Nature of
Technology "is a classic for our times.

The book gives an overview of the current state-of-the-art
concerning the activation and dissolution of cellulose in a broad
variety of solvents. Research on this topic can lead to new
pathways for the utilization of the most abundant terrestrial
biomolecule and may therefore be the basis for new green strategies
towards advanced materials. Leading scientists in the field show
different conceptions for the solubilization of cellulose. The long
history and groundbreaking developments in the field of polymer
chemistry, which are related to this subject, have lead to timely
alternatives to already established methods. In addition to
discussing attempts for the optimization of known dissolving
procedures, this book also details new solvent systems. New
solvents include inorganic and organic salt melts (ionic liquids),
new aqueous media, multi-component organic solvents and the
dissolution under partial derivatization of the polysaccharide. The
opportunities and the limitations of the solvents are demonstrated,
with a particular emphasis on the stability of the solutions and a
possible recycling of the solvent components.
This book illustrates that the new procedures for cellulose
dissolution can lead to a huge number of unconventional
superstructures of regenerated cellulose material, such as fibers
and polymer layers with a thickness in the nanometer range or
aerogels, i.e. regenerates with a highly porous character and a
large surface. Moreover, cellulose blends can be generated via
solutions. The book also contains chapters that show the amazing
potential of solvents for defined modification reactions on the
cellulose backbone. On one hand, it is possible to synthesize known
cellulose derivatives with new substitution patterns both on the
basis of the repeating unit and along the polymer chain. On the
other hand, completely new derivatives are presented which are
hardly accessible via heterogeneous reactions. Consequently, the
book is intended to give a comprehensive overview of procedures for
dissolution of cellulose. It is of interest for scientists new in
the field but is also a timely summary of trends for experts who
are looking for new approaches for problems related to cellulose
shaping or chemical modification.
In his many previous books John Haught established a reputation as
the leading Catholic theological voice in the study of science and
religion. In this work he offers his most systematic theological
reflections on the relation between Christian revelation and the
unfolding story of the universe. In the face of recent discoveries
some maintain their faith by clinging to a pre-scientific
worldview; others conclude that perhaps "the universe has outgrown
the biblical God who is said to be its creator." For Haught,
however, exploration of the "three infinities" - the immense, the
infinitesimal, and the complex - serves as invitation to an
unprecedented appreciation for the grandeur of God, creation,
Christ, and redemption.
