Book Description
The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

Book Description
The majority of data sets collected by researchers in all disciplines are multivariate, meaning that several measurements, observations, or recordings are taken on each of the units in the data set. These units might be human subjects, archaeological artifacts, countries, or a vast variety of other things. In a few cases, it may be sensible to isolate each variable and study it separately, but in most instances all the variables need to be examined simultaneously in order to fully grasp the structure and key features of the data. For this purpose, one or another method of multivariate analysis might be helpful, and it is with such methods that this book is largely concerned. Multivariate analysis includes methods both for describing and exploring such data and for making formal inferences about them. The aim of all the techniques is, in general sense, to display or extract the signal in the data in the presence of noise and to find out what the data show us in the midst of their apparent chaos. An Introduction to Applied Multivariate Analysis with R explores the correct application of these methods so as to extract as much information as possible from the data at hand, particularly as some type of graphical representation, via the R software. Throughout the book, the authors give many examples of R code used to apply the multivariate techniques to multivariate data.

Book Description
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

Book Description
In this pathbreaking book, a well-known feminist and sociologist--who is also the Founding Editor of Gender & Society--challenges our most basic assumptions about gender. Judith Lorber views gender as wholly a product of socialization subject to human agency, organization, and interpretation. In her new paradigm, gender is an institution comparable to the economy, the family, and religion in its significance and consequences. Drawing on many schools of feminist scholarship and on research from anthropology, history, sociology, social psychology, sociolinguistics, and cultural studies, Lorber explores different paradoxes of gender: --why we speak of only two "opposite sexes" when there is such a variety of sexual behaviors and relationships; --why transvestites, transsexuals, and hermaphrodites do not affect the conceptualization of two genders and two sexes in Western societies; --why most of our cultural images of women are the way men see them and not the way women see themselves; --why all women in modern society are expected to have children and be the primary caretaker; --why domestic work is almost always the sole responsibility of wives, even when they earn more than half the family income; --why there are so few women in positions of authority, when women can be found in substantial numbers in many occupations and professions; --why women have not benefited from major social revolutions. Lorber argues that the whole point of the gender system today is to maintain structured gender inequality--to produce a subordinate class (women) that can be exploited as workers, sexual partners, childbearers, and emotional nurturers. Calling into question the inevitability and necessity of gender, she envisions a society structured for equality, where no gender, racial ethnic, or social class group is allowed to monopolize economic, educational, and cultural resources or the positions of power.
