This book has two purposes. First, to introduce the study of work and the workplace as a method for informing the design of computer systems to be used at work. We primarily focus on the predominant way in which the organization of work has been approached within the field of human-computer interaction (HCI), which is from the perspective of ethnomethodology. We locate studies of work in HCI within its intellectual antecedents, and describe paradigmatic examples and case studies. Second, we hope to provide those who are intending to conduct the type of fieldwork that studies of work and the workplace draw off with suggestions as to how they can go about their own work of developing observations about the settings they encounter. These suggestions take the form of a set of maxims that we have found useful while conducting the studies we have been involved in. We draw from our own fieldwork notes in order to illustrate these maxims. In addition we also offer some homilies about how to make observations; again, these are ones we have found useful in our own work.

Pathology of the Human Placenta remains the most comprehensive and authoritative text in the field. It provides extensive information on the normal placenta, encompassing physiology, metabolism, and endocrinology, and covers the full range of placental diseases in great detail. Further chapters are devoted to abortions, molar pregnancies, multiple pregnancies, and legal considerations. This sixth edition of the book has been extensively revised and expanded to reflect the most recent progress in the field, and a brand new chapter has been added on artificial reproductive technology. Some 800 illustrations are included, many of them in color. The detailed index has been further improved and tables updated. Pathology of the Human Placenta will be of enormous value to pathologists and obstetrician-gynecologists alike.

Developmental programming is a rapidly advancing discipline of great importance to basic scientists and health professionals alike. This text integrates, for the first time, contributions from world experts to explore the role of the placenta in developmental programming. The book considers the materno-fetal supply line, and how perturbations of placental development impact on its functional capacity. Chapters examine ways in which environmental, immunological and vascular insults regulate expression of conventional and imprinted genes, along with their impact on placental shape and size, transport, metabolism and endocrine function. Research in animal models is integrated with human clinical and epidemiological data, and questions for future research are identified. Transcripts of discussions between the authors allow readers to engage with controversial issues. Essential reading for researchers in placental biology and developmental programming, as well as specialists and trainees in the wider field of reproductive medicine.
