Plant Hormones: Biosynthesis and Mechanisms of Action is based on
research funded by the Chinese government's National Natural
Science Foundation of China (NSFC). This book brings a fresh
understanding of hormone biology, particularly molecular mechanisms
driving plant hormone actions. With growing understanding of
hormone biology comes new outlooks on how mankind values and
utilizes the built-in potential of plants for improvement of crops
in an environmentally friendly and sustainable manner. This book is
a comprehensive description of all major plant hormones: how they
are synthesized and catabolized; how they are perceived by plant
cells; how they trigger signal transduction; how they regulate gene
expression; how they regulate plant growth, development and defense
responses; and how we measure plant hormones. This is an exciting
time for researchers interested in plant hormones. Plants rely on a
diverse set of small molecule hormones to regulate every aspect of
their biological processes including development, growth, and
adaptation. Since the discovery of the first plant hormone auxin,
hormones have always been the frontiers of plant biology. Although
the physiological functions of most plant hormones have been
studied for decades, the last 15 to 20 years have seen a dramatic
progress in our understanding of the molecular mechanisms of
hormone actions. The publication of the whole genome sequences of
the model systems of Arabidopsis and rice, together with the advent
of multidisciplinary approaches has opened the door to successful
experimentation on plant hormone actions.
In this provocative book, acclaimed psychologists Thomas Ward,
Ronald Finke, and Steven Smith eloquently portray the fascinating
processes of the creative mind at work, and hand us the invaluable
tools with which we can mine our most valued and important
resource. Creativity - and the methods by which we can heighten it
- has recently become the focus of a burgeoning and exciting new
field in psychology. By skillfully blending this cutting-edge
scientific research with the real-world experiences of humanity's
most successful creative thinkers, this provocative book isolates
the mechanisms by which our mind conceives innovative and creative
ideas. Since all creative thoughts emerge from skillfully drawing
upon the well of knowledge we already possess, this book tackles
the very nature of this knowledge. As these astute authors
convincingly argue, the same mental processes that help a chemist
like Kary Mullis discover a revolutionary new scientific principle
or inspire an artist like Beethoven to create a marvelous symphony
underlie the host of creative endeavors we all undertake. This
inspiring book applies these basic tenets to a rich variety of
creative pursuits, including engineering, design, writing,
business, science, art, and even the challenges of our everyday
lives. We learn how best to combine and play with the images,
words, and concepts that spark fertile new ideas and lead to ever
more impressive creative leaps.
Spontaneous resting-state fluctuations in neuronal activity offer
insights into the inherent organization of the human brain, and may
provide markers for diagnosis and treatment of mental disorders.
Resting state functional magnetic resonance imaging (fMRI) can be
used to investigate intrinsic functional connectivity networks,
which are identified based on similarities in the signal measured
from different brain regions. From data acquisition to
interpretation of results, Introduction to Resting State fMRI
Functional Connectivity discusses a wide range of approaches
without requiring any previous knowledge of resting state fMRI,
making it highly accessible to readers from a broad range of
backgrounds. Supplemented with online datasets and examples to
enable the reader to obtain hands-on experience working with real
data, this primer provides a practical and approachable
introduction for those new to the field of resting state fMRI. The
Oxford Neuroimaging Primers are short texts aimed at new
researchers or advanced undergraduates from the biological, medical
or physical sciences. They are intended to provide a thorough
understanding of the ways in which neuroimaging data can be
analyzed and how that relates to acquisition and interpretation.
Each primer has been written so that it is a stand-alone
introduction to a particular area of neuroimaging, and the primers
also work together to provide a comprehensive foundation for this
increasingly influential field.
This book provides a comprehensive introduction to functional magnetic resonance imaging (fMRI), the scanning technique which allows the mapping of active processes within the brain. There are six sections to the book with chapters from an expert international team. Part I provides a broad overview of the field and sets the context. Part II describes the physiological and physical background to fMRI, including coverage of the hardware required and pulse sequence selection. Practical issues involving experimental design of the paradigms, psycho-physical stimulus delivery and subject response are covered in Part III, followed by a comprehensive treatment of data analysis in Part IV. Part V deals with practical applications of the technique in the field of neuroscience and in clinical practice. The final section describes how fMRI can be integrated with other neuro-electromagnetic functional mapping techniques. Functional Magnetic Resonance Imaging: An Introduction to Methods is written to be accessible to a wide-ranging audience of research scientists interested in studying how the normal brain works, and clinicians interested in monitoring disease states and processes.
Background and History Although Cape Cod National Seashore (CACO)
is perhaps best known for its shoreline scenery, the interior
forests and woodlands have become the most prominent feature of
this coastal landscape. In the period before European settlement,
Cape Cod was covered largely by pine-oak forests, interspersed with
smaller areas of hickory (Carya spp.), beech (Fagus grandifolia),
red maple (Acer rubrum), and birch (Betula spp.) (Motzkin et al.
2002). In the 18th and 19th centuries, much of Cape Cod consisted
of open heathlands and grasslands created and maintained primarily
by the agricultural practices of early settlers that included
cutting, grazing, and burning (Eberhardt 2001, Eberhardt et al.
2003). The cessation of these activities by the mid-1800's allowed
trees to re-invade the landscape (Patterson et al. 1983, Motzkin et
al. 2002, Parshall et al. 2003), and forests now occupy the largest
land-surface area and biovolume of any vegetation community (Figure
1).
In 2011, monitoring was conducted to follow up on a 2005 survey of
dune vegetation habitat and for continued development of a
long-term vegetation monitoring protocol for this ecosystem. In
2005, thirty vegetation sampling sites were established in what was
then dune grassland habitat throughout Cape Cod National Seashore
(CACO), arranged along seven transects running perpendicular to the
coastline from Chatham to Provincetown. Each site consisted of two
10x10-m plots. In addition to distance from coastline, sites were
characterized by integrating GIS technology to assess landscape
changes and succession.
This paper begins with a twentieth century look at multilateralism
in East Asia by examining a wealth of expert historical and
contemporary analysis. Next, a potential multilateral framework is
presented with an analysis of the associated benefits and
complexities related to the concept. The key issue of reunification
is also revealed, specifically whether a DPRK government collapse
would equal immediate reunification. Finally, this study concludes
with a look at the implications of using multilateralism in dealing
with this crisis to future U.S. interests in Northeast Asia.
Creative Cognition combines original experiments with existing work
in cognitive psychology to provide the first explicit account of
the cognitive processes and structures that contribute to creative
thinking and discovery. Creative Cognition combines original
experiments with existing work in cognitive psychology to provide
the first explicit account of the cognitive processes and
structures that contribute to creative thinking and discovery. In
separate chapters, the authors take up visualization, concept
formation, categorization, memory retrieval, and problem solving.
They describe novel experimental methods for studying creative
cognitive processes under controlled laboratory conditions, along
with techniques that can be used to generate many different types
of inventions and concepts. Unlike traditional approaches, Creative
Cognition considers creativity as a product of numerous cognitive
processes, each of which helps to set the stage for insight and
discovery. It identifies many of these processes as well as general
principles of creative cognition that can be applied across a
variety of different domains, with examples in artificial
intelligence, engineering design, product development,
architecture, education, and the visual arts. Following a summary
of previous approaches to creativity, the authors present a
theoretical model of the creative process. They review research
involving an innovative imagery recombination technique, developed
by Finke, that clearly demonstrates that creative inventions can be
induced in the laboratory. They then describe experiments in
category learning that support the provocative claim that the
factors constraining category formation similarly constrain
imagination and illustrate the role of various memory processes and
other strategies in creative problem solving.
