The alpine treeline ecotone (ATE) is an area of transition high on
mountains where closed canopy forests from lower elevations give
way to the open alpine tundra and rocky expanses above. Alpine
tundra is an island biome and its ecotone with forest is subject to
change, and like oceanic islands, alpine tundra is subject to
invasion or the upward advance of treeline. The invasion of tundra
by trees will have consequences for the tundra biome as invasion
does for other island flora and fauna. To examine the invasibility
of tundra we take a plant s-eye-view, wherein the local conditions
become extremely important. Among these local conditions, we find
geomorphology to be exceptionally important. We concentrate on
aspects of microtopography (and microgeomorphology) and
microclimate because these are the factors that matter: from the
plant s-eye-view, but we pay attention to multiple scales. At
coarse scales, snow avalanches and debris flows are widespread and
create disturbance treelines whose elevation is well below those
controlled by climate. At medium scales, turf-banked terraces
create tread-and-riser topography that is a difficult landscape for
a tree seedling to survive upon because of exposure to wind,
dryness, and impenetrable surfaces. At fine scales, turf
exfoliation of the fronts of turf-banked risers, and boulders,
offer microsites where tree seedlings may find shelter and are able
to gain a foothold in the alpine tundra; conversely, however,
surfaces of needle-ice pans and frost heaving associated with
miniature patterned ground production are associated with sites
inimical to seedling establishment or survival. We explicitly
consider how local scale processes propagate across scales into
landscape patterns.
The objective of this book is to examine the controls on change at
alpine treeline. All the papers are focused on work done in Glacier
National Park, Montana, USA. Although any one place is limiting, we
are able to examine the alpine treeline here in some detail and an
advantage is that the treeline ecotone in Glacier National Park is
quite variable in itself due to the underlying variability in
geomorphology at multiple scales.
This book will provide insights into an important ecological
phenomenon with a distinctly geomorphic perspective. The editors
collectively have over 100 years of experience in working in
geomorphology, biogeography, and ecology. They also have each
worked on research in Glacier National Park for several decades.
The book will be a reference for a variety of professionals and
students, both graduate and undergraduate, with interests in
Physical Geography, Geomorphology, Ecology, and Environmental
Science. Because of the importance of the alpine treeline ecotone
for recreation and aesthetic interests in mountain environments,
wildland and park managers will also use this book.
* Subject matter: geomorphology at alpine treeline
* Expertise of contributors: each editor brings over 25 years of
experience in studies of ecotones and geomorphology, and
collectively over 100 years of experience in Glacier National
Park
* Changing alpine treeline examines climate change"
The controversy surrounding the significant "Into the Heart of
Africa" exhibit at the Royal Ontario Museum in Canada is explored
in this compelling and analytical text. The exhibit has become an
international, controversial touchstone for issues surrounding the
politics of visual representation, such as the challenges to
curatorial and ethnographic authority in multicultural and
postcolonial contexts. Asking why the museum's exhibit failed so
many people, the author examines such issues as institutional
politics, the broad political and intellectual climate surrounding
museums, the legacies of colonialism and traditions of
representation of Africa, and the politics of irony.
By drawing upon anthropological and cultural criticism, the book
offers a unique account of the ways in which an ambiguous exhibit
about colonialism became the site of an expansiveInto the Heart of
Africa."
Through an exclusive focus on public policy advocacy, Dalton and
Butler offer practical guidance for determining the fundamental
issues that make up a controversy and what expectations public
audiences will have for advocacy based on the issues and the
burdens of advocates challenging or defending the status quo.
Through examples that span a wide range of advocacy situations and
subjects of contemporary importance, the authors build a framework
for public policy advocacy that is organic to the communication
discipline, recover and refresh foundational lessons about the uses
of evidence, and provide critical questions that can be used to
develop and communicate policy proposals that are sensible and
appealing. Written in an accessible, respectful, and motivational
style, the book is suitable for students of debate, professionals
who function as advocates, and people who wish to voice their
opinion.
Have you ever been so deep in love that you found yourself doing
things you never imagined? Love can lift you high above the
mountains but it can also drive you to the deepest valleys. Even
though it sometimes fails you, you can't help but give it another
try. LOVE WILL DO THAT takes you through an array of emotions,
which forces you to evaluate what is important. It cuts through the
red tape and takes you to the core of the heart...the place where
love truly abides.
Through an exclusive focus on public policy advocacy as a practical
endeavor, Philip Dalton and John R. Butler depart from approaches
to debate education that focus on the rules of simulated, academic
debate formats. Beginning with the assumption that readers have
already developed a basic capacity to argue, they offer practical
guidance for determining the fundamental issues that make up a
controversy and what expectations public audiences will have for
advocacy based on the issues and the burdens of advocates
challenging or defending the status quo. Through examples that span
a wide range of advocacy situations and subjects of contemporary
importance, the authors build a framework for public policy
advocacy that is organic to the communication discipline, recover
and refresh foundational lessons about the uses of evidence, and
provide critical questions that can be used to develop and
communicate policy proposals that are sensible and appealing.
Written in an accessible, respectful, and motivational style, the
book is suitable for students of debate, professionals who function
as advocates, and people who find themselves wishing to voice their
opinion on an issue of concern.

Dendrogeomorphology Beginnings and Futures: A Personal Reminiscence
My early forays into dendrogeomorphology occurred long before I
even knew what that word meant. I was working as a young
geoscientist in the 1960s and early 1970s on a problem with slope
movements and deformed vegetation. At the same time, unknown to me,
Jouko Alestalo in Finland was doing something similar. Both of us
had seen that trees which produced annual growth rings were
reacting to g- morphic processes resulting in changes in their
internal and external growth p- terns. Dendroclimatology was an
already well established field, but the reactions of trees to other
environmental processes were far less well understood in the 1960s.
It was Alestalo (1971) who first used the term,
dendrogeomorphology. In the early 1970s, I could see that active
slope-movement processes were affecting the growth of trees in
diverse ways at certain localities. I wanted to learn more about
those processes and try to extract a long-term chronology of
movement from the highly diverse ring patterns.
Managing Natural Science Collections demonstrates the need for
consistency and evidence-based decision making in the management of
natural science collections, which are becoming increasingly
valuable when it comes to addressing societal challenges. Drawing
upon the experience of four experts who have managed some of the
largest and most diverse collections in the world, the book aims to
assist in the making of strategic and operational decisions
regarding care, development, access and resource management.
Encouraging the reader to consider how collection strategies can be
aligned with the mission of their institution and contribute to its
vision, the authors also examine ways to deliver a consistent
approach that will secure the present and future availability and
relevance of collections. Principles of good practice and resource
optimisation in an ethical and legal context are provided
throughout the book, as well as case studies, sample documents and
templates, all of which will be useful for discussion and teaching.
Managing Natural Science Collections encourages each reader to
consider the different options available to them. As such, it
should be essential reading for museum practitioners and other
professionals around the world who are involved with any strategic
aspect of managing natural science collections. Students of museum
studies will also find much to interest them within the pages of
this book.
In this book, Dr. Shirley R. Butler-Derge examines Rites of Passage
programs and whether they are an effective and necessary
educational tool to improve academic performance and
self-confidence among male African American high school students a
demographic group that has statistically struggled in both
standardized testing results and grade point averages. Dr. Shirley
R. Butler-Derge provides commentary on the effectiveness of these
programs as well as some necessary components that must be
incorporated when developing and implementing Rites of Passage
programs."

This book is devoted to the Anthropocene, the period of
unprecedented human impacts on Earth's environmental systems, and
illustrates how Geographers envision the concept of the
Anthropocene. This edited volume illustrates that geographers have
a diverse perspective on what the Anthropocene is and represents.
The chapters also show that geographers do not feel it necessary to
identify only one starting point for the temporal onset of the
Anthropocene. Several starting points are suggested, and some
authors support the concept of a time-transgressive Anthropocene.
Chapters in this book are organized into six sections, but many of
them transcend easy categorization and could have fit into two or
even three different sections. Geographers embrace the concept of
the Anthropocene while defining it and studying it in a variety of
ways that clearly show the breadth and diversity of the discipline.
This book will be of great value to scholars, researchers, and
students interested in geography, environmental humanities,
environmental studies, and anthropology. The chapters in this book
were originally published as a special issue of the journal Annals
of the American Association of Geographers.

Manufacturing the Future: A History of Western Electric is the first full-length history of the Western Electric Company, the manufacturing arm of the Bell System. As a manufacturer in the communications revolutions in the nineteenth and twentieth centuries, Western Electric made new products such as telegraphs, telephones, an early computing machine, radios, radar, and transistors. The book demonstrates, through Western's 1882 acquisition by Bell Telephone, that vertical integration was a lengthy process rather than a single event. It also shows the coming of age of industrial psychology and describes the advent of civil rights in corporate America.
For the first time, the proceedings of our biennial congress of the
Society for Forensic Haemogenetics will be published by
Springer-Verlag Berlin Heidelberg New York. The different areas of
research now include cellu- lar allotypes, i. e. not only the
traditional red cell antigens, but also those of white cells and
platelets. Plasma isoproteins and intracellular isoenzy- mes, DNA
polymorphisms (restriction length fragment and banding), and
biostatistics are further topics in our Society. They also deserve
our special attention in the future. The practical applications
comprise paren- tage testing, stain analysis, population genetics,
molecular biology and other immunogenetic aspects. The 11th
Congress in Copenhagen was an excellent opportunity to pre- sent
our broad spectrum of scientific activities at an international
forum. Among the many outstanding lectures from different parts of
the world, D. A. Hopkinson's contribution on genetic variation of
human enzymes and H. Matsumoto's lecture on immunoglobulin
allotypes in China should be mentioned here and also L. Bolund's
communication on DNA. An optimal exchange of scientific information
was achieved by the arrangement of main lectures, poster sessions
and workshops. The Con- gress president Dr. Klavs Henningsen
deserves our special thanks for his efforts in the excellent
organization of this congress.

This is a full-length history of the Western Electric Company,
which was the manufacturing arm of the Bell System. As manufacturer
in the communications revolutions in the nineteenth and twentieth
centuries, Western Electric made products that accelerated
society's pace, such as telegraphs, telephones, an early computing
machine, radios, radar and transistors. Western's history offers
numerous examples of the difference between innovation and
implementation. The aftermath of Western's 1882 acquisition by Bell
Telephone, for instance, reveals vertical integration as a lengthy
process rather than a single event. Ironically, although Western
transformed business worldwide with innovations in areas such as
quality control and industrial psychology, the company was slow to
implement these innovations itself. Western's dual role as captive
supplier for a regulated monopoly and as government contractor led
to its most rapid change, in the area of civil rights.
Animals as geomorphic agents have primarily been considered
"curiosities" in the literature of geomorphology, whose spatial and
quantitative influences have been seen as both limited and minor.
Zoogeomorphology: Animals as Geomorphic Agents examines the
distinct geomorphic influences of invertebrates, ectothermic
vertebrates, birds, and mammals, and demonstrates the importance of
animals as landscape sculptors. Specific processes associated with
the diversity of animal influences in geomorphology are examined,
including burrowing and denning, nesting, lithophagy and geophagy,
wallowing and trampling, food caching, excavating for food, and dam
building by beavers. Particular emphasis is placed on terrestrial
animals, although aquatic animals are also discussed where
appropriate. This book, which is the only one available wholly
devoted to this topic, will interest graduate students and
professional research workers in geomorphology, ecology,
environmental science, physical geography, and geology.
