Book excerpt: 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 excerpt: Some colleges will do anything to improve their national ranking. That can be bad for their students—and for higher education. Since U.S. News & World Report first published a college ranking in 1983, the rankings industry has become a self-appointed judge, declaring winners and losers among America's colleges and universities. In this revealing account, Colin Diver shows how popular rankings have induced college applicants to focus solely on pedigree and prestige, while tempting educators to sacrifice academic integrity for short-term competitive advantage. By forcing colleges into standardized "best-college" hierarchies, he argues, rankings have threatened the institutional diversity, intellectual rigor, and social mobility that is the genius of American higher education. As a former university administrator who refused to play the game, Diver leads his readers on an engaging journey through the mysteries of college rankings, admissions, financial aid, spending policies, and academic practices. He explains how most dominant college rankings perpetuate views of higher education as a purely consumer good susceptible to unidimensional measures of brand value and prestige. Many rankings, he asserts, also undermine the moral authority of higher education by encouraging various forms of distorted behavior, misrepresentation, and outright cheating by ranked institutions. The recent Varsity Blues admissions scandal, for example, happened in part because affluent parents wanted to get their children into elite schools by any means necessary. Explaining what is most useful and important in evaluating colleges, Diver offers both college applicants and educators a guide to pursuing their highest academic goals, freed from the siren song of the "best-college" illusion. Ultimately, he reveals how to break ranks with a rankings industry that misleads its consumers, undermines academic values, and perpetuates social inequality.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Ranking of people, schools, products, countries, and just about everything else is part of our daily lives. But we are in a paradoxical relationship with ranking: we believe that ranking is good because it is informative and objective; and we believe ranking is bad because it is biased and subjective, and occasionally, even manipulated. Ranking: The Unwritten Rules of the Social Game We All Play combines the application of scientific theories to everyday experience with entertaining personal stories.

Available in PDF, EPUB and Kindle. Book excerpt: Anthropological enquiry is best done by attending equally to both social and cultural material. This is the view propounded here by Marvin Davis, who uses such an holistic approach to develop an original perspective on hierarchy and politics in rural Bengal. In the first part of the book, Professor Davis describes the indigenous theory of rank held by Hindus in rural West Bengal and shows that the premise of inequality is a central organising principle of their entire society and cosmos. In the second part, he shows that the Bengali preoccupation with rank generates frequent political rivalries at each level of rural social organisation. His book will interest all anthropologists and other social scientists concerned with the social and political organization of rural India. In addition, his explication of the links between ideology and social structure, often viewed in isolation from each other, makes the book an important contribution to anthropological theory and method.

Available in PDF, EPUB and Kindle. Book excerpt: The mathematics behind today's most widely used rating and ranking methods A website's ranking on Google can spell the difference between success and failure for a new business. NCAA football ratings determine which schools get to play for the big money in postseason bowl games. Product ratings influence everything from the clothes we wear to the movies we select on Netflix. Ratings and rankings are everywhere, but how exactly do they work? Who's #1? offers an engaging and accessible account of how scientific rating and ranking methods are created and applied to a variety of uses. Amy Langville and Carl Meyer provide the first comprehensive overview of the mathematical algorithms and methods used to rate and rank sports teams, political candidates, products, Web pages, and more. In a series of interesting asides, Langville and Meyer provide fascinating insights into the ingenious contributions of many of the field's pioneers. They survey and compare the different methods employed today, showing why their strengths and weaknesses depend on the underlying goal, and explaining why and when a given method should be considered. Langville and Meyer also describe what can and can't be expected from the most widely used systems. The science of rating and ranking touches virtually every facet of our lives, and now you don't need to be an expert to understand how it really works. Who's #1? is the definitive introduction to the subject. It features easy-to-understand examples and interesting trivia and historical facts, and much of the required mathematics is included.

Available in PDF, EPUB and Kindle. Book excerpt: Much has changed for workers in the years since Staughton and Alice Lynd's classic Rank and File: Personal Histories by Working-Class Organizers was first published in 1973. The New Rank and File presents interviews with working-class organizers of the 1970s, 1980s, and 1990s who face the challenges of a new economy with the same determination and creativity shown by those profiled in the earlier book. Reflecting the increasing globalization of labor practices—and problems—The New Rank and File contains oral histories of workers in Guatemala, Palestine, Nicaragua, Mexico, and Canada, as well as the United States.In their narratives, rank-and-file workers from many different industries and workplaces reveal the specific incidents and pervasive injustices that triggered their activism. They discuss the frustrations they faced in attempting to effect change through traditional means, and the ways in which they have learned to advocate through innovation. In an incisive introduction, the Lynds set forth their distinctive perspective on the labor movement, with a focus on "solidarity unionism": making decisions on the assumption that we all may be leaders at one time or another rather than relying on static hierarchies. Their insights, along with true stories told in the organizers' own words, contain much to inspire a new generation of workers and activists.Jim BrophyTony BudakAndrea CarneyChinese Staff and Workers' AssociationCoalition of University EmployeesBill DiPietroKay EisenhowerRich FeldmanThe Frente Autentico del TrabajoMarshall GanzMia GiuntaMartin GlabermanMayra GuillenThe Hebron Union of Workers and General Service PersonnelHugo HernandezMargaret KeithElly LearyEd MannCharlie McCollesterVirginia RomanVicky StarrGary StevensonMike StoutManuela Aju TambrizJames TrevathanTriState Conference on SteelMauricio VallejosWorkers for Ford in Mexico

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.

Book excerpt: This book explains how to analyze independent data from factorial designs without having to make restrictive assumptions, such as normality of the data, or equal variances. The general approach also allows for ordinal and even dichotomous data. The underlying effect size is the nonparametric relative effect, which has a simple and intuitive probability interpretation. The data analysis is presented as comprehensively as possible, including appropriate descriptive statistics which follow a nonparametric paradigm, as well as corresponding inferential methods using hypothesis tests and confidence intervals based on pseudo-ranks. Offering clear explanations, an overview of the modern rank- and pseudo-rank-based inference methodology and numerous illustrations with real data examples, as well as the necessary R/SAS code to run the statistical analyses, this book is a valuable resource for statisticians and practitioners alike.

Available in PDF, EPUB and Kindle. Book excerpt: Students and the public routinely consult various published college rankings to assess the quality of colleges and universities and easily compare different schools. However, many institutions have responded to the rankings in ways that benefit neither the schools nor their students. In Engines of Anxiety, sociologists Wendy Espeland and Michael Sauder delve deep into the mechanisms of law school rankings, which have become a top priority within legal education. Based on a wealth of observational data and over 200 in-depth interviews with law students, university deans, and other administrators, they show how the scramble for high rankings has affected the missions and practices of many law schools. Engines of Anxiety tracks how rankings, such as those published annually by the U.S. News & World Report, permeate every aspect of legal education, beginning with the admissions process. The authors find that prospective law students not only rely heavily on such rankings to evaluate school quality, but also internalize rankings as expressions of their own abilities and flaws. For example, they often view rejections from “first-tier” schools as a sign of personal failure. The rankings also affect the decisions of admissions officers, who try to balance admitting diverse classes with preserving the school’s ranking, which is dependent on factors such as the median LSAT score of the entering class. Espeland and Sauder find that law schools face pressure to admit applicants with high test scores over lower-scoring candidates who possess other favorable credentials. Engines of Anxiety also reveals how rankings have influenced law schools’ career service departments. Because graduates’ job placements play a major role in the rankings, many institutions have shifted their career-services resources toward tracking placements, and away from counseling and network-building. In turn, law firms regularly use school rankings to recruit and screen job candidates, perpetuating a cycle in which highly ranked schools enjoy increasing prestige. As a result, the rankings create and reinforce a rigid hierarchy that penalizes lower-tier schools that do not conform to the restrictive standards used in the rankings. The authors show that as law schools compete to improve their rankings, their programs become more homogenized and less accessible to non-traditional students. The ranking system is considered a valuable resource for learning about more than 200 law schools. Yet, Engines of Anxiety shows that the drive to increase a school’s rankings has negative consequences for students, educators, and administrators and has implications for all educational programs that are quantified in similar ways.
