An exciting look at the essential roles that parasites play in
Earth's ecosystems This book looks at the weird and wonderful world
of parasites, the most abundant form of life on Earth. Parasites
come in all forms and sizes and inhabit every free-living organism.
Parasitism is now, and always has been, a way to survive under
changing environmental conditions. From arctic oceans to tropical
forests, Scott Gardner, Judy Diamond, and Gabor Racz investigate
how parasites survive and evolve, and how they influence and
provide stability to ecosystems. Taking readers to the open ranges
of Mongolia, the Sandhills of north-central Nebraska, the Andes of
Bolivia, and more, the authors examine the impact parasites have on
humans and other animals. Using examples of parasites from
throughout the tree of life, the authors describe parasite-host
relationships as diverse as those between trematodes and snails and
tapeworms and whales. They even consider the strange effects of
thorny-headed worms on their hosts. Parasites offer clues to the
evolutionary history of particular regions, and they can provide
insights into the history of species interactions. Through
parasites, biologists can weave together a global knowledge of the
past to predict the challenges that we will face in the future.
Revealing that parasites are so much more than creepy-crawlies,
this book gives up-to-date context for these critical members of
the biological diversity of our planet.

This book discusses the issue of academic misconduct and
publication ethics in general and plagiarism in particular, with a
focus on case studies in various universities around the world
(notably in Japan, Singapore, Australia, USA, and Canada). We are
especially interested in students' and teachers' perception of
academic misconduct and their definition and understanding of
plagiarism. Most chapters discuss undergraduates' understanding of
academic dishonesty and students' experiences using plagiarism
softwares. The book also analyzes teachers' perception of cheating
and how they respond to it. Writing is perceived by all of the
teachers to be the most important form of assessment that required
preventative measures in order to reduce the occurrence of academic
dishonesty among students. Each chapter recommends strategies to
fight plagiarism, such as establishing guidelines and regulations
concerning academic integrity, awareness of the scale of the issue
(scandals at all levels in most countries, even including famous
scholars, administrators, and elected officials), assessing the
damage done to academic reputation and credibility, developing
trust and credibility on social media (especially with the recent
disturbing growth of fake news and data), minimizing the
proliferation of dishonest accreditation, of identity theft, of
fake peer-reviews, and fighting the growing number of fake papers,
with or without the use of computer-generated academic works.
"Value Assumptions in Risk Assessment" is a case study of the
Alachlor Controversy of 1985 in which the Canadian Minister of
Agriculture cancelled the registration of the herbicide alachlor.
This book demonstrates the opinion that risk assessments by
scientific experts as well as ordinary citizens are guided by
dominant values held by the assessors. It examines what these
values typically are, how they work within a risk assessment, and
some implications of reconsidering risk debates as primarily
debates about values.
Throughout, the book draws the conclusion that such debates are
not primarily debates about science itself, but rather consist of
political debate among different value frameworks, different ways
of thinking about moral values, different conceptions of society,
and different attitudes toward technology and toward risk-taking
itself. The larger question in the analysis of these risk
assessments is which set of values will ultimately prevail.
