Originally published in 1960, the two volumes of Experiments in Personality report a number of experiments in psychogenetics, psychopharmacology, psychodiagnostics, psychometrics and psychodynamics, all of which formed part of the programme of research which had been developing from the late 1940s at the Maudsley Hospital. Presenting the studies together in a book, rather than the more usual route of journal articles, was itself felt to be an experiment at the time, especially given the wide area covered. The decision was deliberate because all the studies reported formed part of a larger whole, which would have been lost if published separately. Volume I looks at psychogenetics and psychopharmacology.

Originally published in 1926, the first part of this book attempted to formulate a theory of ability in the light of recent experimental results of the time. It discusses the nature of intelligence and the problem of special abilities, and includes a study of some typical forms of genius. The second part gives an account of a three years' experimental study of special abilities in arts and science respectively, carried out upon university students. Samples of the tests employed are included. The results are presented in non-technical form. Victoria Hazlitt was a pioneer of experimental psychology, which was particularly significant as a woman in the early twentieth century. In many cases her work anticipated later developments in psychology by many years. Today it can be enjoyed in its historical context.

This book shows readers how to conduct observational methods, research tools used to describe and explain behaviors as they unfold in everyday settings. The book now uses both an evolutionary and a cultural perspective. The methods presented are drawn from psychology, education, family studies, sociology, and anthropology, but the author's primary focus is on children in school, family, and social settings. Readers learn how to make observations in real contexts to help them create a verbal picture of behaviors they see. The importance of considering reliability and validity factors while testing within each environment is emphasized throughout. The author draws from the literature that provides methods for observing animals in their natural habitats, but emphasizes the use of observational methods to solve human problems. The book is organized in the way a researcher conducts observational studiesOCoconceptualizing of the idea, designing and implementing the study, and writing the report. OC Things to think aboutOCO sections provide an opportunity for students to solidify their understanding of the material and the Glossary defines the key terms introduced in the book.

Highlights of changes in the new edition include:

OCoaThe introduction of the cultural perspective in chapter 4 along with the evolutionary (epigenetic theory) perspective and the integration of cultural examples throughout the book.
OCoaMore varied examples from developmental psychology, family studies, and education.
OCoaExtensively revised chapter (3) on ethics reflects the current revelations of scientific fraud and the push for researchers to maximize scientific integrity in their community.
OCoaUpdated chapter (12) reflects the latest computer technologies used in observational methods including iPhones and Blackberrys for conducting observation, ABC Data Pro and Behavior Tracker for evaluations, and Excel for constructing observational templates.
OCoaExpanded chapter (13) on writing the research report and more on issues of plagiarism (ch. 3).a
OCoaThe latest on minimizing observer effects on participants and testing their effectiveness.
OCoaNew environmentally friendly design, the Things to Think About sections were retained, but the blank pages for answers were eliminated.

Intended as a supplementary text for advanced undergraduate and/or graduate courses in research methods and/or developmental research or developmental/child psychology taught in psychology, education, human development, and nursing, educators and researchers concerned with assessing children will also appreciate this bookOCOs introduction to observational methods.

High stakes tests are the gatekeepers to many educational and professional goals. As such, the incentive to cheat is high. This Handbook is the first to offer insights from experts within the testing community, psychometricians, and policymakers to identify and develop best practice guidelines for the design of test security systems for a variety of testing genres. Until now this information was scattered and often resided inside testing companies. As a result, rather than being able to learn from each other's experiences, each testing entity was left to re-create their own test security wheel. As a whole the book provides invaluable insight into the prevalence of cheating and "best practices" for designing security plans, training personnel, and detecting and investigating misconduct, to help develop more secure testing systems and reduce the likelihood of future security breaches. Actual case studies from a variety of settings bring to life how security systems really work. Examples from both domestic and international programs are provided. Highlights of coverage include:* Best practices for designing secure tests * Analysis of security vulnerabilities for all genres of testing * Practical cheating prevention and detection strategies * Lessons learned in actual security violations in high profile testing programs. Part I focuses on how tests are delivered for paper-and-pencil, technology-based, and classroom testing and writing assessment. Each chapter addresses the prevalence of the problem and threats to security, prevention, and detection. Part II addresses issues essential to maintaining a secure testing program such as planning and monitoring, physical security, the detection of group-based cheating, investigating misconduct, and communicating about security-related issues. Part III examines actual examples of cheating-- how the cheating was done, how it was detected, and the lessons learned. Part III provides insight into security issues within each of the Association of Test Publishers' four divisions: certification/licensure, clinical, educational, and industrial/organizational testing. Part III's conclusion revisits the issues addressed in the case studies and identifies common themes. Intended for organizations, professionals, educators, policy makers, researchers, and advanced students that design, develop, or use high stakes tests, this book is also ideal for graduate level courses on test development, educational measurement, or educational policy.

Although its roots can be traced to the 19th century, progress in the study of nonlinear dynamical systems has taken off in the last 30 years. While pertinent source material exists, it is strewn about the literature in mathematics, physics, biology, economics, and psychology at varying levels of accessibility. A compendium research methods reflecting the expertise of major contributors to NDS psychology, Nonlinear Dynamical Systems Analysis for the Behavioral Sciences Using Real Data examines the techniques proven to be the most useful in the behavioral sciences. The editors have brought together constructive work on new practical examples of methods and application built on nonlinear dynamics. They cover dynamics such as attractors, bifurcations, chaos, fractals, catastrophes, self-organization, and related issues in time series analysis, stationarity, modeling and hypothesis testing, probability, and experimental design. The analytic techniques discussed include several variants of the fractal dimension, several types of entropy, phase-space and state-space diagrams, recurrence analysis, spatial fractal analysis, oscillation functions, polynomial and Marquardt nonlinear regression, Markov chains, and symbolic dynamics. The book outlines the analytic requirements faced by social scientists and how they differ from those of mathematicians and natural scientists. It includes chapters centered on theory and procedural explanations for running the analyses with pertinent examples and others that illustrate applications where a particular form of analysis is seen in the context of a research problem. This combination of approaches conveys theoretical and practical knowledge that helps you develop skill and expertise in framing hypotheses dynamically and building viable analytic models to test them.

The comprehensive reference for informative WISC-V assessment Essentials of WISC-V Assessmentprovides step-by-step guidance for administering, scoring, and interpreting the Wechsler Intelligence Scale for Children (WISC-V). Packed with practical tips for more accurate assessment, this informative guide includes numerous case studies that illustrate a range of real-world issues. Special attention is devoted to the assessment of individuals who have significant learning difficulties, such as learning disabilities, and who speak English as a second language. The WISC-V is a valuable assessment tool, but it must be administered and scored appropriately to gain meaning from score interpretation. This book gives you an in-depth understanding of the WISC-V assessment and interpretive process to assist practitioners in: * Conducting efficient and informative WISC-V assessments * Utilizing WISC-V in cross-battery and neuropsychological assessment * Applying WISC-V in the identification of specific learning disabilities * Utilizing WISC-V in nondiscriminatory assessment of English language learners * Writing theory-based WISC-V reports * Linking WISC-V findings to interventions based on individual performance As the world's most widely-used intelligence test for children, the WISC-V is useful in diagnosing intellectual disabilities and specific learning disabilities, as well as in identifying giftedness. In this volume, sample reports demonstrate how WISC-V assessment results may be linked to interventions, accommodations, modifications, and compensatory strategies that facilitate positive outcomes for children. Essentials of WISC-V Assessment is the all-in-one practical resource for both students and practitioners. The book can be used on its own or with companion software (purchased separately) that provides a user-friendly tool for producing psychometrically and theoretically defensible interpretations of WISC-V performance, and may be used to develop interventions based on each child's strengths and weaknesses.

What exactly is narcissism? An incurable disease set to ruin your future, a habit to be curbed, or a trait to be nurtured? And how can you tell if your partner, child, or even you are a narcissist? Dr Craig Malkin offers a new picture of narcissism, showing us why being called a 'narcissist' isn't necessarily such a bad thing after all. Narcissism is all around us. We are a selfie-obsessed generation, surviving on a steady diet of watching reality shows that celebrate attention-seeking know-and-do-nothings and posting a whopping 500 million tweets a day to document our every thought and whim. But is narcissism really as bad as we have been led to believe? In this groundbreaking book, clinical psychologist Dr Craig Malkin offers a radically new picture of narcissism, defining it as a spectrum of self-importance, and explaining that everyone falls somewhere on the scale between utter selflessness and total arrogance. He reveals why it is essential to embrace some level of narcissism in order to maintain a healthy sense of self-worth. Feeling special, to a degree, can make us better lovers and partners, courageous leaders, and intrepid explorers. As supportive as it is illuminating, The Narcissist Test is the first and only book to distinguish between healthy and unhealthy narcissism, and offers clear, step-by-step guidance on how to promote the healthy kind in your partner, children, and in yourself. From advice tailored to parents, social media users and even schools, this is the definitive text to help you overcome the bad - and embrace the good - about feeling special. Dr Craig Malkin is a clinical psychologist hailing from Harvard with over two decades of experience helping individuals, couples and families.

Adapting Educational and Psychological Tests for Cross-Cultural Assessment critically examines and advances new methods and practices for adapting tests for cross-cultural assessment and research. The International Test Commission (ITC) guidelines for test adaptation and conceptual and methodological issues in test adaptation are described in detail, and questions of ethics and concern for validity of test scores in cross-cultural contexts are carefully examined. Advances in test translation and adaptation methodology, including statistical identification of flawed test items, establishing equivalence of different language versions of a test, and methodologies for comparing tests in multiple languages, are reviewed and evaluated. The book also focuses on adapting ability, achievement, and personality tests for cross-cultural assessment in educational, industrial, and clinical settings. This book furthers the ITC's mission of stimulating research on timely topics associated with assessment. It provides an excellent resource for courses in psychometric methods, test construction, and educational and/or psychological assessment, testing, and measurement. Written by internationally known scholars in psychometric methods and cross-cultural psychology, the collection of chapters should also provide essential information for educators and psychologists involved in cross-cultural assessment, as well as students aspiring to such careers.

A focused look at the usesand misusesof psychological tests in the context of child custody This book presents an advanced examination of psychological testing and usage in the child custody arena. It addresses test selection issues, provides insightful discussions of how to confront confirmatory biases and avoid the distortion of test findings, and presents clear instructions for the use of specific tests, including MMPI-2 and Rorschach, and a point/counterpoint discussion of the strengths and weaknesses of the Ackerman-Schoendorf Scales for Parent Evaluation of Custody (ASPECT). Psychological Testing in Child Custody Evaluations can be viewed as a work in three parts. The first section addresses theoretical and test usage issues, with chapters focusing on: addressing test selection issues from legal and psychological perspectives bias issues that interfere with the evaluator's ability to collect and consider data objectively a functional, comprehensive approach to the use of psychological tests in a child custody evaluationwith a conceptual framework for choosing assessment techniques to assess parenting competencies and other variables important in forming opinions about custodial placement and visitation access, and a practical example of how to present psychological test data in an advisory report to the court a look at psychological testing from an attorney's point of view The second section of Psychological Testing in Child Custody Evaluations focuses on the MMPI-2 and the Rorschach Inkblot Test in the child custody context, investigating hypotheses that can be inferred from the MMPI-2 regarding parenting behaviors, and the use and value of the Rorschach. This section examines: the foundation from which the MMPI-2 can generate expectations regarding five basic issuesthe quality of attachment and bonding, potential for antisocial behavior, temper control, alienation of affection, and chemical abuse and dependence the range of variables that will generate useful hypotheses regarding parent-child interactions and family systems the effects of the circumstances of litigation on score elevationsincluding recommended limits as to how much elevation can be dismissed as only contextual the important differences between occasion validity and attribute validity the clinical application of an objective interpretation system, including the courtroom credibility of explicit convergent validity the use of the Rorschach in child custody evaluations findings from a study using the Rorschach to address specific parenting variables The third section of Psychological Testing in Child Custody Evaluations is a focused point-counterpoint discussion of ASPECT, between test creator Marc J. Ackerman and Mary Connell, President of the American Academy of Forensic Psychology. This book is essential reading for child custody evaluators, family law attorneys, and judges practicing in the family law arena, as well as educators and students in these fields.

Recognised as the most influential publication in the field, ARM facilitates deep understanding of the Rasch model and its practical applications. The authors review the crucial properties of the model and demonstrate its use with examples across the human sciences.

Professionals in these areas will also appreciate the book’s accessible introduction.

An Introduction to Psychometrics and Psychological Assessment is the successor to Cooper’s prize-winning book Psychological Testing: Theory and Practice. This expanded and updated volume shows how psychological questionnaires and tests can be chosen, administered, scored, interpreted and developed. In providing students, researchers, test users, test developers and practitioners in the social sciences, education and health with an evaluative guide to choosing, using, interpreting and developing tests, it provides readers a thorough grasp of the principles (and limitations) of testing, together with the necessary methodological detail.

This book has three distinctive features. First, it stresses the basic logic of psychological assessment without getting bogged down with mathematics; the spreadsheet simulations and utilities which are integrated into the text allow users to explore how numbers behave, rather than reading equations. Readers will "learn by doing". Second, it covers both the theory behind psychological assessment and the practicalities of locating, designing and using tests and interpreting their scores. Finally, it is evaluative. Rather than just describing concepts such as test reliability or adaptive testing, it stresses the underlying principles, merits and drawbacks of each approach to assessment, and methods of developing and evaluating questionnaires and tests. Unusually for an introductory text, it includes coverage of several cutting-edge techniques, and this new edition expands the discussion on measurement invariance, methods of detecting/quantifying bias and hierarchical factor models, and features added sections on:

Best practices for translation of tests into other languages and problems of cultural bias

Automatic item generation

The advantages, drawbacks and practicalities of internet-based testing

Generalizability theory

Network analysis

Dangerous assumptions made when scoring tests

The accuracy of tests used for assessing individuals

The two-way relationship between psychometrics and psychological theory

Aimed at non-mathematicians, this friendly and engaging text will help you to understand the fundamental principles of psychometrics that underpin the measurement of any human characteristic using any psychological test. Written by a leading figure in the field and accompanied by additional resources, including a set of spreadsheets which use simulated data and other techniques to illustrate important issues, this is an essential introduction for all students of psychology and related disciplines. It assumes very little statistical background and is written for students studying psychological assessment or psychometrics, and for researchers and practitioners who use questionnaires and tests to measure personality, cognitive abilities, educational attainment, mood or motivation.

This edited volume presents a balanced approach to the ongoing debate of just how general the "general factor" of intelligence is. To accomplish this goal, the editors chose a number of distinct approaches to the study of intelligence--psychometric, genetic-epistemological, cognitive, biological, behavior-genetic, sociocultural, systems--and asked distinguished scholars to write from the standpoint of these approaches. Each approach comprises two chapters, one by a scholar leaning toward a view arguing for the greater generality of "g," and the other by a scholar leaning toward a view arguing for the lesser generality of "g." The scholars are not simply "for" or "against" these outlooks, rather they provide a more textured view of the general factor, attempting to explain it in psychological terms that are easily understandable.
Intended for psychologists in all areas, including clinical, consulting, educational, cognitive, school, developmental, and industrial-organizational, this book will also be of interest to educators, sociologists, anthropologists, and those interested in the nature of intelligence.

El objetivo del libro es proporcionar a los lectores las herramientas necesarias para evaluar la calidad psicome trica de las medidas educativas y psicolo gicas, asi como de encuestas y cuestionarios.

Asumimos un nivel ba sico de conocimientos estadi sticos, pero estos conceptos se ira n repasando a lo largo de los diferentes capi tulos. Nos imaginamos que este texto (a) esperara pacientemente en algunos despachos implorando ser entregado, como recurso, a un estudiante, (b) tendra un lugar fijo en las mesas de los despachos donde continuamente, y debido a su uso diario, sera el primero del monto n, (c) estara en las mochilas de los estudiantes de postgrado, y los acompan ara felizmente desde casa al trabajo o a las clases y vuelta, (d) aparecera orgullosamente como un texto de referencia en los programas y guia s de estudio, y finalmente (e) como ocasional posavasos mientras se reflexiona profundamente acerca de co mo resolver los problemas de medida. Esperamos que a trave s de estos usos, sobre todo el u ltimo, aportar algu n conocimiento y ayuda que permita a los lectores aplicar adecuadamente las te cnicas y los conceptos abordados en este manual. The goal of the book is to provide readers with the tools necessary for assessing the psychometric qualities of educational and psychological measures as well as surveys and questionnaires. Each chapter will cover an issue pertinent to psychometric and measurement practice, with an emphasis on application. Topics will be briefly discussed from a theoretical/technical perspective in order to provide the reader with the background necessary to correctly use and interpret the statistical analyses that will be presented subsequently. The anticipated audience for this book includes researchers, practitioners, and graduate students searching for a guide to perform common psychometric analyses on various assessments, as discussed in many psychometric texts. We envision that this text will (a) patiently wait on some office shelves begging to be handed to a student as a resource, (b) have a permanent home on desks where it continually rises to the top of the stacks for daily use of the applied researcher, (c) be happily carried in bags to and from work and class by the graduate student learning techniques, (d) be listed proudly as a reference text on syllabi, and finally (e) as an occasional drink coaster while deep thoughts are pondered about how to solve measurement problems. We hope that through such uses, particularly the latter, that we have provided some insight and assistance to the user in appropriately applying the techniques and concepts discussed.

Many psychological factors are little more than statistical descriptions of particular sets of data and have no real significance. Paul Kline uses his long and extensive knowledge of psychological measurement to argue that truly scientific forms of measurement could be developed to create a new psychometrics. This would transform the basis of psychology and change it from a social science to a pure science.

Why are some people more mentally able than others ? In an authoritative, critical and intergrated series of review essays Professor Ian Deary inquires after the cognitive and biological foundations of human mental ability differences. Many accounts of intelligence have examined the structure and number of human mental ability differences and whether they can predict sucess in education,work and social life. Few books have taken psychometric intelligence differences as a starting point and brought together the reductionistic attempts to explain them.New to the highly acclaimed Oxford Psychology Series, Looking Down on Human Intelligence appraises the search for the origins of psychometric intelligence differences in terms of brain function parameters. The book provides an original and thought provoking guide to ancient and modern research on one of the most compelling questions in human psychology.

This book examines the principles and practice of authentic assessment. It seeks to answer the following questions. What is authentic assessment? How is authentic assessment different from 'performance assessment' or 'alternative assessment'? How can authentic assessment support learner-centred education, especially when a performance-oriented culture favours pen-and-paper examinations? The book is structured into two major parts. The first, 'Principles of authentic assessment design', provides readers with a conceptual explanation of authenticity; the principles for designing quality authentic assessments for valid evidence of student learning; and guidance about how to develop quality rubrics to structure assessment tasks. The second part of the book, 'Theory into practice' provides examples developed by teachers to demonstrate an understanding of authentic assessment. The subject areas covered include humanities, languages, mathematics, sciences, character and citizenship. Two case studies are discussed to demonstrate how authentic assessment can be used to comprehensively address key learning objectives in a variety of curriculum contexts. This book provides practitioners with concrete examples on how to develop authentic assessment to suit their context and also enhance their students' learning. The book will also enable teachers to face assessment challenges present in our changing world.

A SPECTATOR BOOK OF THE YEAR 'History that reads like biography that reads like a novel - a fluid narrative that defies expectations and plays against type' New York Times 'Brilliant and savage' Philip Hensher An unprecedented history of the personality test conceived a century ago by a mother and her daughter - fiction writers with no formal training in psychology - and how it insinuated itself into our boardrooms, classrooms, and beyond. The Myers-Briggs Type Indicator is the most popular personality test in the world. It has been harnessed by Fortune 100 companies, universities, hospitals, churches, and the military. Its language - of extraversion vs. introversion, thinking vs. feeling - has inspired online dating platforms and Buzzfeed quizzes alike. And yet despite the test's widespread adoption, experts in the field of psychometric testing, a $500 million industry, struggle to account for its success - no less validate its results. How did the Myers-Briggs insinuate itself into our jobs, our relationships, our internet, our lives? First conceived in the 1920s by the mother-daughter team of Katherine Briggs and Isabel Briggs Myers, a pair of aspiring novelists and devoted homemakers, the Myers-Briggs was designed to bring the gospel of Carl Jung to the masses. But it would take on a life of its own, reaching from the smoke-filled boardrooms of mid-century New York to Berkeley, California, where it was honed against some of the 20th century's greatest creative minds. It would travel across the world to London, Zurich, Cape Town, Melbourne, and Tokyo; to elementary schools, nunneries, wellness retreats, and the closed-door corporate training sessions of today. Drawing from original reporting and never-before-published documents, What's Your Type? examines nothing less than the definition of the self - our attempts to grasp, categorise and quantify our personalities. Surprising and absorbing, the book, like the test at its heart, considers the timeless question: What makes you you?

Practice prepare and get ready to pass. Don't let a psychometric test stop you getting the job you want. Packed with practice questions and practical Passing Psychometric Tests will help you lose the fear, prepare and practice with everything you need to know to pass with flying colours.

This book demonstrates the importance of computer-generated statistical analyses in behavioral science research, particularly those using the R software environment. Statistical methods are being increasingly developed and refined by computer scientists, with expertise in writing efficient and elegant computer code. Unfortunately, many researchers lack this programming background, leaving them to accept on faith the black-box output that emerges from the sophisticated statistical models they frequently use. Building on the author's previous volume, Linear Models in Matrix Form, this text bridges the gap between computer science and research application, providing easy-to-follow computer code for many statistical analyses using the R software environment. The text opens with a foundational section on linear algebra, then covers a variety of advanced topics, including robust regression, model selection based on bias and efficiency, nonlinear models and optimization routines, generalized linear models, and survival and time-series analysis. Each section concludes with a presentation of the computer code used to illuminate the analysis, as well as pointers to packages in R that can be used for similar analyses and nonstandard cases. The accessible code and breadth of topics make this book an ideal tool for graduate students or researchers in the behavioral sciences who are interested in performing advanced statistical analyses without having a sophisticated background in computer science and mathematics.

The field of psychometrics has a long and varied tradition across the social sciences. A range of academics have sought to understand human consciousness more fully by statistical testing our abilities, personalities, attitudes and beliefs. But perhaps the area where psychometric techniques have had most impact on contemporary society is in employee recruitment, where a range of psychometric tests have become common-place. Professor Peter Saville is one of the pioneers of adapting psychometric testing to the field of occupational psychology and human resource management. In a career of nearly 40 years, his work has been adopted by hundreds of public and private organizations, assessing the suitability of prospective candidates through a range of questionnaires and tests. In this anthology of his work, including both keynote conference address and journal papers, Saville provides a masterly overview of the field of psychometrics, and the key issues and questions that it raises. An ideal companion for any student or researcher of HRM, occupational or organizational psychology, or applied psychology in general, Peter Saville's selected works represent the thinking of one of the most influential psychologists of our time.

This new edition suggests new directions for research and practice, includes emphasis on modern computers and technology useful in assessment, and pays more attention to prediction of individual growth and globalization challenges in the assessment process. The book will be of interest to faculty and students in Industrial Organizational psychology, human resource management and business. IO psychologists in private business and public sector organizations who have responsibilities for staffing and an interest in measurement and statistics will find this book useful.

This book introduces multidimensional scaling (MDS) and unfolding as data analysis techniques for applied researchers. MDS is used for the analysis of proximity data on a set of objects, representing the data as distances between points in a geometric space (usually of two dimensions). Unfolding is a related method that maps preference data (typically evaluative ratings of different persons on a set of objects) as distances between two sets of points (representing the persons and the objects, resp.). This second edition has been completely revised to reflect new developments and the coverage of unfolding has also been substantially expanded. Intended for applied researchers whose main interests are in using these methods as tools for building substantive theories, it discusses numerous applications (classical and recent), highlights practical issues (such as evaluating model fit), presents ways to enforce theoretical expectations for the scaling solutions, and addresses the typical mistakes that MDS/unfolding users tend to make. Further, it shows how MDS and unfolding can be used in practical research work, primarily by using the smacof package in the R environment but also Proxscal in SPSS. It is a valuable resource for psychologists, social scientists, and market researchers, with a basic understanding of multivariate statistics (such as multiple regression and factor analysis).

"Automated scoring engines [...] require a careful balancing of the contributions of technology, NLP, psychometrics, artificial intelligence, and the learning sciences. The present handbook is evidence that the theories, methodologies, and underlying technology that surround automated scoring have reached maturity, and that there is a growing acceptance of these technologies among experts and the public." From the Foreword by Alina von Davier, ACTNext Senior Vice President Handbook of Automated Scoring: Theory into Practice provides a scientifically grounded overview of the key research efforts required to move automated scoring systems into operational practice. It examines the field of automated scoring from the viewpoint of related scientific fields serving as its foundation, the latest developments of computational methodologies utilized in automated scoring, and several large-scale real-world applications of automated scoring for complex learning and assessment systems. The book is organized into three parts that cover (1) theoretical foundations, (2) operational methodologies, and (3) practical illustrations, each with a commentary. In addition, the handbook includes an introduction and synthesis chapter as well as a cross-chapter glossary.
