March 2021International Trade in Forest Products
Lumber Trade Disputes, Models and Examples
by G Cornelis van Kooten, Linda Voss
Because of the long-standing Canada-U.S. lumber trade dispute and the current pressure on the world's forests as a renewable energy source, much attention has been directed toward the modelling of international trade in wood products. Two types of trade models are described in this book: one is rooted in economic theory and mathematical programming, and the other consists of two econometric/statistical models--a gravity model rooted in theory and an approach known as GVAR that relies on time series analyses. The purpose of the book is to provide the background theory behind models and facilitate readers in easily constructing their own models to analyse policy questions that they wish to address, whether in forestry or some other sector. Examples in the book are meant to illustrate how models can be used to say something about a variety of issues, including identification of the gains and losses to various players in the North American softwood lumber business, and the potential for redirecting sales of lumber to countries outside the United States. The discussion is expanded to include other products besides lumber, and used to examine, for example, the effects of log export restrictions by one nation on all other forestry jurisdictions, the impacts of climate policies as they relate to the global forest sector, and the impact of oil prices on forest product markets throughout the world. This book will appeal to practising economists and researchers who wish to examine various policies that affect international trade, whether their interest is local or international in scope. Because the book provides the theoretical bases underlying various models, students and practitioners will find this a valuable reference book or supplementary textbook.

January 2021Practical R for Biologists
An Introduction
by Donald Quicke, Buntika A Butcher, Rachel Kruft Welton
R is a freely available, open-source statistical programming environment which provides powerful statistical analysis tools and graphics outputs. R is now used by a very wide range of people; biologists (the primary audience of this book), but also all other scientists and engineers, economists, market researchers and medical professionals. R users with expertise are constantly adding new associated packages, and the range already available is immense.This text works through a set of studies that collectively represent almost all the R operations that biology students need in order to analyse their own data. The material is designed to serve students from first year undergraduates through to those beginning post graduate levels. Chapters are organized around topics such as graphing, classical statistical tests, statistical modelling, mapping, and text parsing. Examples are based on real scientific studies, and each one covers the use of more R functions than those simply necessary to get a p-value or plot.The book walks the reader through the data analysis process, starting with very simple plots, and continuing through more complex analyses and programming. It shows how to deal with issues such as error messages that can be confronting for beginners, in order to set students up for a successful scientific career using R.Collectively the authors have a vast amount of teaching experience which they apply here to make the passage into R programming as gentle and easy as possible, whilst guiding the reader to tackle quite complicated programming. Table of contents 1: How to Use this Book 2: Installing and Running R 3: Very Basic R Syntax 4: First Simple Programs and Graphics 5: The Dataframe Concept 6: Plotting Biological Data in Various Ways 7: The Grammar of Graphics Family of Packages 8: Sets and Venn diagrams 9: Statistics: Choosing the Right Test 10: Commonly Used Measures and Statistical Tests 11: Regression and Correlation Analyses 12: Count Data as Response Variable 13: Analysis of Variance (ANOVA) 14: Analysis of Covariance (ANCOVA) 15: More Generalised Linear Modelling 16: Monte Carlo Tests and Randomisation 17: Principal Components Analysis 18: Species Abundance, Accumulation and Diversity Data 19: Survivorship 20: Dates and Julian Dates 21: Mapping and Parsing Text Input for Data 22: More on Manipulating Text 23: Phylogenies and Trees 24: Working with DNA Sequences and other character data 25: Spacing in Two Dimensions 26: Population Modelling Including Spatially Explicit Models 27: More on “apply” Family of Functions – Avoid Loops to get More Speed 28: Food webs and simple graphics 29: Adding Photographs 30: Standard Distributions in R 31: Reading and Writing Data to and from Files

Science & MathematicsApril 2022Nematodes as Model Organisms
by Itamar Glazer, David I Shapiro-llan, Paul W. Sternberg
Nematodes, which are small multi cellular organisms have been used as biological models since the 1960's. The nematode worm Caenorhabditis elegans is a free-living nematode, about 1mm in length, that lives in temperate soil environments. It is made up of about 1000 cells, and has a short life cycle of only 2 weeks. It was the first multicellular organism to have its whole genome sequenced. The book includes chapters that summarize the importance of nematodes as model organisms in the fields of genetics, developmental biology, neurobiology, pharmacology, nutrition, ecology and parasitology. Of interest to a broad audience across a wide spectrum of disciplines, the book is useful for biologists working on comparative studies to investigate biological processes across organisms; medical scientists and pharmacologist for exploration of drugs and medicine (including the use of genome editing to eliminate diseases); ecologists considering nematodes as indicators for environment changes; and parasitologists for host-parasite interactions. Many other researchers can use this book as a benchmark for the broad implications of nematology research on other aspects of science.

MedicineTheory and Model of Physiotherapy
by Heidi Höppner, Robert Richter (editors)
How will physiotherapy adapt to developments and challenges in the 21st century? New thinking while keeping the tried-and-tested: This is the motto adopted by eight physiotherapy researchers and practitioners in this handbook. Their contributions advance the theory for their discipline. They have met regularly at the so-called Berlin Salon since 2015: they analyze, discuss, and incorporate existing models and adopt a theory. They are all professionally qualified physiotherapists with further training in fields such as health science, education, and therapy management. They all suffer from the lack of theory in professional practice, and they have all experienced the diverse, often unconscious discourses in the field. Theoretical understanding and theory development require theory-driven reflection, the results of which have long since left the Berlin Salon and been adopted internationally. Target Group: Physiotherapists, healthcare scientists, university instructors

Literature & Literary StudiesMarch 2017Imperialism and juvenile literature
by Jeffrey Richards
Popular culture is invariably a vehicle for the dominant ideas of its age. Never was this truer than in the late-nineteenth and early twentieth centuries, when it reflected the nationalist and imperialist ideologies current throughout Europe. It both reflects popular attitudes, ideas and preconceptions and it generates support for selected views and opinions. This book examines the various media through which nationalist ideas were conveyed in late-Victorian and Edwardian times: in the theatre, "ethnic" shows, juvenile literature, education and the iconography of popular art. It seeks to examine in detail the articulation and diffusion of imperialism in the field of juvenile literature by stressing its pervasiveness across boundaries of class, nation and gender. It analyses the production, distribution and marketing of imperially-charged juvenile fiction, stressing the significance of the Victorians' discovery of adolescence, technological advance and educational reforms as the context of the great expansion of such literature. An overview of the phenomenon of Robinson Crusoe follows, tracing the process of its transformation into a classic text of imperialism and imperial masculinity for boys. The imperial commitment took to the air in the form of the heroic airmen of inter-war fiction. The book highlights that athleticism, imperialism and militarism become enmeshed at the public schools. It also explores the promotion of imperialism and imperialist role models in fiction for girls, particularly Girl Guide stories.

History of Art / Art & Design StylesDecember 2006Model and supermodel
The artists' model in British art and culture
by Edited by Jane Desmarais, Martin Postle and Martin Vaughan
Over the last twenty years there have been flurries of interest in the artist's model, and recent exhibitions have stimulated new activity in this area. Model and Supermodel extends the discussion about the social and cultural significance of the model in British art and culture. A fascinating collection of essays and interviews, it examines the persistent mythology of the artist's model and some of the ambiguities involved in depicting the body. The volume begins with Martin Postle's survey of the profession of the model during the period c.1840-1940. Elizabeth Prettejohn considers the Pre-Raphaelite model and Alison Smith examines the lives of some nineteenth-century models who achieved fame and notoriety in their own right. Jane Desmarais looks at the model from a literary perspective and Reena Suleman presents the work of Edward Linley Sambourne. Michael Hatt's essay examines the aesthetic and ethical aspects of Tuke's use of boy models for his paintings of nude bathers, and William Vaughan reflects on the British figurative tradition from Sickert to Freud. Catherine Wood brings the volume up to date with her essay on the found model in contemporary art, and the volume concludes with two interviews with the artist, Peter Blake, and a life model, Susannah Gregory. The book offers a series of lively takes on the phenomenon of the artist's model. It will make fascinating reading for those interested in modern art and the wider aspects of British culture and society.
