Book Description
Due to the fast growth of the Web and the difficulties in finding desired information, efficient and effective information retrieval systems have become more important than ever, and the search engine has become an essential tool for many people. The ranker, a central component in every search engine, is responsible for the matching between processed queries and indexed documents. Because of its central role, great attention has been paid to the research and development of ranking technologies. In addition, ranking is also pivotal for many other information retrieval applications, such as collaborative filtering, definition ranking, question answering, multimedia retrieval, text summarization, and online advertisement. Leveraging machine learning technologies in the ranking process has led to innovative and more effective ranking models, and eventually to a completely new research area called “learning to rank”. Liu first gives a comprehensive review of the major approaches to learning to rank. For each approach he presents the basic framework, with example algorithms, and he discusses its advantages and disadvantages. He continues with some recent advances in learning to rank that cannot be simply categorized into the three major approaches – these include relational ranking, query-dependent ranking, transfer ranking, and semisupervised ranking. His presentation is completed by several examples that apply these technologies to solve real information retrieval problems, and by theoretical discussions on guarantees for ranking performance. This book is written for researchers and graduate students in both information retrieval and machine learning. They will find here the only comprehensive description of the state of the art in a field that has driven the recent advances in search engine development.

Book Description
A disrobing acrobat, a female Hamlet, and a tuba-playing labor activist--all these women come to life in Rank Ladies. In this comprehensive study of women in vaudeville, Alison Kibler reveals how female performers, patrons, and workers shaped the rise and fall of the most popular live entertainment at the turn of the century. Kibler focuses on the role of gender in struggles over whether high or low culture would reign in vaudeville, examining women's performances and careers in vaudeville, their status in the expanding vaudeville audience, and their activity in the vaudevillians' labor union. Respectable women were a key to vaudeville's success, she says, as entrepreneurs drew women into audiences that had previously been dominated by working-class men and recruited female artists as performers. But although theater managers publicly celebrated the cultural uplift of vaudeville and its popularity among women, in reality their houses were often hostile both to female performers and to female patrons and home to women who challenged conventional understandings of respectable behavior. Once a sign of vaudeville's refinement, Kibler says, women became associated with the decay of vaudeville and were implicated in broader attacks on mass culture as well.

Book Description
Economic theory is growing not only in depth but in the breadth of its application as well. This study encroaches in part on a field normally considered as the domain of Sociology. But the methods applied here are those of mathematical economics. It has not been my ambition to make this as general and as mathe matically demanding as possible. On the contrary, I wanted to present as simple an argument as possible throughout. I wish to thank Brown University for granting me a Sabbatical leave in the Fall of 1977-78 in the course of which I wrote the first draft of this monograph. I am also grateful to the late Professor Jacob Marschak and to Professor Arthur Geoffrion for sponsoring me as a Visiting Scholar of the Western Management Science Institute, Graduate School of Management, UCLA for the months of November and December 1977. The Western Management Science Institute proved to be an ideal environment for writing: protective and stimulating at the same time. I have benefitted specifically from comments received as a result of presenting Chapters IV and V in the Marschak Colloquium on December 2, 1977, in particular by Professors Intri11igator and Spiro. My greatest indebtedness is to Jacob Marschak to whom I owe my awareness of and interest in the economic theory of organizations. He was my teacher, my director and supervisor, and my fatherly friend since 1950. It is thus entirely fitting that this work should be dedicated to his memory.

Book Description
And Another Thing ... will be the sixth novel in the now improbably named Hitchhiker's Guide to the Galaxy trilogy. Eight years after the death of its creator, Douglas Adams, the author's widow, Jane Belson, has given her approval for the project to be continued by the international number one bestselling children's writer, Eoin Colfer, author of the Artemis Fowl novels. Douglas Adams himself once said, 'I suspect at some point in the future I will write a sixth Hitchhiker book. Five seems to be a wrong kind of number, six is a better kind of number.' Belson said of Eoin Colfer, 'I love his books and could not think of a better person to transport Arthur, Zaphod and Marvin to pastures new.' Colfer, a fan of Hitchhiker since his schooldays, said, 'Being given the chance to write this book is like suddenly being offered the superpower of your choice. For years I have been finishing this incredible story in my head and now I have the opportunity to do it in the real world.' Prepare to be amazed...

Book Description
Based on ten years of research, the book follows individuals and families as they apply for and live on public aid and eventually leave the system. Rank's chronicle of their day-to-day experiences reveals the many sacrifices and crises that tax ordinary people in extraordinary ways. Beginning with a history of welfare from Roosevelt to Clinton, he focuses on AFDC and the Food Stamp program. He then describes the backgrounds of the recipients, their hopes for the future and attitudes toward welfare, their daily routines and problems, their work behavior, and the effect of welfare on family dynamics. Living on the Edge reveals the experiences of female-headed families, married couples, single men and women, and the elderly.
