An exploration of the geography by which measles has repeatedly passed through a series of communities in Iceland during the 20th century. Demonstrates the general principles which underlie person-to-person spatial diffusion processes.

Friendships are crucial to children's well-being and happiness and lay important foundations upon which later relationships in adolescence and adulthood are built. This overview of the nature and significance of children's peer relationships examines issues such as social-cognitive development; the context of children's relationships; relationship problems such as loneliness; shyness and social isolation; and methods of promoting positive relationships.

This original textbook provides a comprehensive and integrated approach to using quantitative methods in the social sciences. Thomas R Black guides the student and researcher through the minefield of potential problems that may be confronted, and it is this emphasis on the practical that distinguishes his book from others which focus exclusively on either research design and measurement or statistical methods. Focusing on the design and execution of research, key topics such as planning, sampling, the design of measuring instruments, choice of statistical text and interpretation of results are examined within the context of the research process. In a lively and accessible style, the student is introduced to researc design issues alongside statistical procedures and encouraged to develop analytical and decision-making skills.

Plants have cultural histories, as their applications change over time and with place. Some plant species have affected human cultures in profound ways, such as the stimulants tea and coffee from the Old World, or coca and quinine from South America. Even though medicinal plants have always attracted considerable attention, there is surprisingly little research on the interface of ethnobotany and medical anthropology. This volume, which brings together (ethno-)botanists, medical anthropologists and a clinician, makes an important contribution towards filling this gap. It emphasises that plant knowledge arises situationally as an intrinsic part of social relationships, that herbs need to be enticed if not seduced by the healers who work with them, that herbal remedies are cultural artefacts, and that bioprospecting and medicinal plant discovery can be viewed as the epitome of a long history of borrowing, stealing and exchanging plants.

All human life unfolds within a matrix of relations, which are at once social and biological. Yet the study of humanity has long been divided between often incompatible 'social' and 'biological' approaches. Reaching beyond the dualisms of nature and society and of biology and culture, this volume proposes a unique and integrated view of anthropology and the life sciences. Featuring contributions from leading anthropologists, it explores human life as a process of 'becoming' rather than 'being', and demonstrates that humanity is neither given in the nature of our species nor acquired through culture but forged in the process of life itself. Combining wide-ranging theoretical argument with in-depth discussion of material from recent or ongoing field research, the chapters demonstrate how contemporary anthropology can move forward in tandem with groundbreaking discoveries in the biological sciences.
