Book Description
This book provides step-by-step instructions on how to analyze text generated from in-depth interviews and focus groups, relating predominantly to applied qualitative studies. The book covers all aspects of the qualitative data analysis process, employing a phenomenological approach which has a primary aim of describing the experiences and perceptions of research participants. Similar to Grounded Theory, the authors' approach is inductive, content-driven, and searches for themes within textual data.

Book Description
This unique text provides a broad introduction to qualitative analysis together with concrete demonstrations and comparisons of five major approaches. Leading scholars apply their respective analytic lenses to a narrative account and interview featuring "Teresa," a young opera singer who experienced a career-changing illness. The resulting analyses vividly exemplify what each approach looks like in action. The researchers then probe the similarities and differences among their approaches; their distinctive purposes and strengths; the role, style, and subjectivity of the individual researcher; and the scientific and ethical complexities of conducting qualitative research. Also included are the research participant's responses to each analysis of her experience. A narrative account from another research participant, "Gail," can be used by readers to practice the kinds of analysis explored in the book.

Book Description
An up-to-date, comprehensive account of major issues in finitemixture modeling This volume provides an up-to-date account of the theory andapplications of modeling via finite mixture distributions. With anemphasis on the applications of mixture models in both mainstreamanalysis and other areas such as unsupervised pattern recognition,speech recognition, and medical imaging, the book describes theformulations of the finite mixture approach, details itsmethodology, discusses aspects of its implementation, andillustrates its application in many common statisticalcontexts. Major issues discussed in this book include identifiabilityproblems, actual fitting of finite mixtures through use of the EMalgorithm, properties of the maximum likelihood estimators soobtained, assessment of the number of components to be used in themixture, and the applicability of asymptotic theory in providing abasis for the solutions to some of these problems. The author alsoconsiders how the EM algorithm can be scaled to handle the fittingof mixture models to very large databases, as in data miningapplications. This comprehensive, practical guide: * Provides more than 800 references-40% published since 1995 * Includes an appendix listing available mixture software * Links statistical literature with machine learning and patternrecognition literature * Contains more than 100 helpful graphs, charts, and tables Finite Mixture Models is an important resource for both applied andtheoretical statisticians as well as for researchers in the manyareas in which finite mixture models can be used to analyze data.

Book Description
"The authors take a ′user friendly′ systematic approach to qualitative research, something that has long been missing in the field. I consider this to be a groundbreaking work, one that will hit home with students and faculty alike." —Justin M. Laird, SUNY Brockport "This book does an excellent job of integrating design, methods, and analysis. . . . The real beauty of the book is that it overturns many of the age-old assumptions about how ′good′ research should be done. . . . The authors′ pleasant and refreshing style, coupled with subtle irreverence for outmoded or constraining paradigms of inquiry, makes for highly enjoyable reading." —Roger Rennekamp, University of Kentucky Interactive Qualitative Analysis: A Systems Method for Qualitative Research aims to help students unscramble the mysteries of qualitative data collection, coding, and analysis by showing how to use a systematic, qualitative technique: interactive qualitative analysis. The authors synthesize ideas from grounded theory, path and factor analysis, quality management theory, Foucauldian concepts of power and knowledge, and systems theory. A dialectical revision of Guba and Lincoln′s theory of rigor is offered which, combined with systems theory, offers new insights into the meaning of reliability and validity in qualitative research. Unlike many theoretical works, Interactive Qualitative Analysis develops the theory into a complete and transparent set of protocols for research design, observation, analysis, and interpretation. The construction, interpretation, and comparison of recursive systems of meaning, or mindmaps, is articulated in detail. The book is organized so that those not interested in theory can skip to the applied chapters. Case studies illustrate each stage of the research process with an emphasis on interpretation. The combination of theory and practice perfectly suits the book for advanced qualitative research courses across the social sciences, especially those that address epistemology. Professional researchers and evaluators will also find this an invaluable guide to qualitative analysis. Key Features * Advice boxes alert readers to potential pitfalls in qualitative research, and offer the appropriate steps to take in order to avoid such issues * Sidebars provide clear and concise snapshots of the theoretical basis for research decisions * Interactive CD contains sample data and exercises to provide students with effective practice as well as reinforce and clarify principles explained in the book * Provides a "road map" to using interactive qualitative inquiry in dissertation writing
