In the last 60 years fertiliser use in agriculture has increased by
900%. However, itâs been reported that up to 80% of these
fertilisers are not utilised by crops but are lost to the
environment as nitrous oxide, ammonia and nitrate. Improving
nitrogen use efficiency is recognised as one possible solution to
reducing the sectorâs environmental impact and optimising its
productivity and sustainability in the face of increasing pressure
to feed a growing population. Improving nitrogen use efficiency in
crop production reviews recent advances in understanding nitrogen
cycling in soil and best practices to assess crop nitrogen status,
such as the use of proximal sensors and remote sensing techniques.
The book considers developments in the use of inorganic nitrogen
fertilisers and their effectiveness in optimising nitrogen use
efficiency, as well as how more organic sources of nitrogen, such
as livestock manure, can be optimised to achieve the same goal.
In this book ? a landmark text that is both engaging and
accessible ? Hilary Janks addresses the following questions and
many more:
- Is literacy a skill or a social practice?
- In what ways is literacy embodied?
- Do texts have designs on us and what can we do about it?
- How does language construct reality?
- What is 'linguistic capital' and who has it?
- Who gets access to new literacies and who is excluded?
- How is literacy implicated in relations of power and questions
of identity in our daily lives?
Janks shows how competing orientations to critical literacy
education ? domination (power), access, diversity, design ?
foreground one over the other. Her central argument is that these
different orientations are crucially interdependent and need to
work together to create possibilities for redesign and social
action that serve a social justice agenda. Recognizing ongoing
change in socio-historical conditions, in the communication
landscape, and in the applications of critical literacy, she
examines the theory underpinning each orientation, and develops new
theory in the argument for interdependence and integration. Most
important, Literacy and Power sits at the interface between theory
and practice, constantly moving from one to the other. It is rich
with examples of how to use these orientations in real teaching
contexts, and how to use them to counterbalance one another.
In the groundbreaking final chapter, Janks shows ways of working
'beyond reason'. Considering how the rationalist underpinning of
critical literacy tends to exclude the non-rational ? pleasure and
play, desire and the unconscious ? she makes the case that these
need to be taken seriously given their power to cut across the work
of critical literacy educators working from any orientation.
Existing research methods textbooks emphasize the mechanics of HOW
to conduct research studies. However, many students fail to see WHY
it is important to learn about research because they will never
conduct research studies. These students do not become engaged in
learning and believe that research courses and textbooks are
useless. They do not see the need of developing "research literacy"
to understand the applications and limitations of research to their
daily lives. This book engages students with a nonmathematical
presentation that includes real examples of the consequences of
research errors in daily life. The organization facilitates
learning with objectives, concepts, description of errors, best
practices, and examples. This is a research methods textbook for
students who fear research textbooks. The diversity of topics in
this book permits application to research methods courses in these
academic fields: Economics, Education, Political Science,
Psychology, and Sociology. This should be the first book for all
students to introduce research and develop "research literacy".
Our society faces international challenges from cyber attacks and
dissemination of fake news with a goal to destabilize our society.
Fake news can be used as a weapon with destructive effects as
powerful as any military attack. Fake news can spread as fast as a
wildfire carried on the winds of social media. Students and all
citizens need to be prepared and informed of ways to quickly
understand and distinguish real and fake news. Preventing the
potential destructive effects of fake news is the purpose of this
book. The focus is upon providing a resource for educators to
develop "news literacy" skills of students in objectively
evaluating the news.

Compelling and highly engaging, this text shows teachers at all
levels how to do critical literacy in the classroom and provides
models for practice that can be adapted to any context. Integrating
social theory and classroom practice, it brings critical literacy
to life as a socio-cultural orientation to the teaching of literacy
that takes seriously the relationship between language and power
and orients readers to the social effects of texts. Students and
teachers are drawn into the key questions critical readers need to
pose of texts: Whose interests are served, who benefits, who is
disadvantaged; who is included and who is excluded? The practical
activities help readers grasp complex issues.
Extending the theoretical framework in Hilary JanksOCO "Literacy
and Power" with a rich range of completely new, up-to-date
activities that translate theory into practice, "Doing Critical
Literacy" is powerful, relevant, and useful for both pre- and
in-service teacher education and for use in schools. "
Get the latest sustainable agriculture practices and keep an eye on
the future Developing and Extending Sustainable Agriculture: A New
Social Contract explores the challenges faced by today's farmers
and ranchers to provide practical strategies to develop a
twenty-first century system of sustainable agriculture that is
economically sound, environmentally compatible, and socially
acceptable. This comprehensive look at the current state of farming
and ranching presents leading authorities discussing concepts and
approaches in sustainable agriculture such as crop rotations,
integrated pest management, alternative sources of nutrients to
maintain productivity, and rotational grazing systems. Presently
there is a trend toward a more industrial agriculture and a global
food system that will bring long-term negative impacts. If farmers
look thoughtfully toward the future, alternatives are now available
to help solve these problems to provide agricultural sustainability
for generations to come. Developing and Extending Sustainable
Agriculture: A New Social Contract provides a model for integrated
research and outreach to everyone interested in sustainable
development. A sensible framework of practical short-term
strategies are combined with visionary long-term plans to provide
viable approaches to sustain agriculture, secure our food system,
and develop a more equitable society for the future. The text
includes several tables and figures, extensive references, and
comprehensive bibliographies. Topics in Developing and Extending
Sustainable Agriculture: A New Social Contract include: the
evolution of the concept of equitable and sustainable development
on-farm research farmer to farmer education IPM (integrated pest
management) soil management managed grazing whole-farm planning,
including economic analysis training for sustainable agriculture
motivation theory and research to foster positive sustainable
development organic farming productivity the future of sustainable
agriculture much, much more Developing and Extending Sustainable
Agriculture: A New Social Contract is enlightening,
horizon-expanding reading perfect for educators, students,
government decision makers, cooperative extension educators,
specialists, administrators, citizen members of county extension
boards, and administrators in land grant universities.
The aim of the book is to present the state of the art of the
theory of symmetric (Hermitian) matrix Riccati equations and to
contribute to the development of the theory of non-symmetric
Riccati equations as well as to certain classes of coupled and
generalized Riccati equations occurring in differential games and
stochastic control. The volume offers a complete treatment of
generalized and coupled Riccati equations. It deals with
differential, discrete-time, algebraic or periodic symmetric and
non-symmetric equations, with special emphasis on those equations
appearing in control and systems theory. Extensions to Riccati
theory allow to tackle robust control problems in a unified
approach.
The book is intended to make available classical and recent
results to engineers and mathematicians alike. It is accessible to
graduate students in mathematics, applied mathematics, control
engineering, physics or economics. Researchers working in any of
the fields where Riccati equations are used can find the main
results with the proper mathematical background.
Clifford Algebras continues to be a fast-growing discipline, with
ever-increasing applications in many scientific fields. This volume
contains the lectures given at the Fourth Conference on Clifford
Algebras and their Applications in Mathematical Physics, held at
RWTH Aachen in May 1996. The papers represent an excellent survey
of the newest developments around Clifford Analysis and its
applications to theoretical physics. Audience: This book should
appeal to physicists and mathematicians working in areas involving
functions of complex variables, associative rings and algebras,
integral transforms, operational calculus, partial differential
equations, and the mathematics of physics.
