When liberal political philosophers talk of equalizing, increasing or maximizing freedom (or liberty), they implicitly assume freedom to be a measurable attribute. Freedom is one of the currencies of a liberal theory of distributive justice, and is therefore assumed to be something that individuals can possess in varying degrees. Yet it is rarely clear what is meant by claims about degrees of freedom. To make sense of such claims, we need to clarify the concept of overall freedom and ask whether its measurement is theoretically possible. This concept is important because freedom has, for liberals, non-specific (or content-independent) value–i.e. value that is independent of the value of being free to do specific things. Liberals prescribe not only that individuals have certain specific freedom-types but also that they have a measure of (overall) freedom. Attempts to make sense of the concept of overall freedom by weighting particular options in terms of their values are erroneous, as these do not account for freedom’s non-specific value. On the other hand, a closer examination of the problems of the individuation of actions and of the various types of constraints on freedom shows overall freedom to be measurable in a way that reflects its non-specific value. To this end, actions need to be individuated in spatio-temporal terms and constraints on freedom need to be characterized in terms of the physical compossibility of actions. The comparative judgements about freedom implied by this analysis (with reference both to individuals and to groups) are more coherent with our intuitive judgements than might at first be expected.

This book draws from a foundation of positive psychology and recently emerging positive organizational behavior (POB). Its purpose is to introduce the untapped human resource capacity of psychological capital, or simply PsyCap. This PsyCap goes beyond traditionally recognized human and social capital and must meet the scientific criteria of theory, research, and valid measurement. To distinguish from other constructs in positive psychology and organizational behavior, to be included in PsyCap the resource capacity must also be “state-like” and thus open to development (as opposed to momentary states or fixed traits) and have performance impact. The positive psychological resource capacities that meet these PsyCap criteria — efficacy (confidence), hope, optimism, and resilience — are covered in separate chapters. These four resource capacities are conceptually and empirically distinct, but also have underlying common processes for striving to succeed and when in combination contribute to a higher-order, core construct of psychological capital. Besides these four, other potential positive constructs such as creativity, wisdom, well being, flow, humor, gratitude, forgiveness, emotional intelligence, spirituality, authenticity, and courage are covered in Chapters 6 and 7. The concluding Chapter 8 summarizes and presents the research demonstrating the performance impact of PsyCap, the PsyCap questionnaire (PCQ) for measurement and the PsyCap Intervention (PCI) for development. Utility analysis indicates that investing in the development of PsyCap can result in a very substantial return. In total, this book provides the theory, research, measure, and method of application for the new resource of Psychological Capital that can be developed and sustained for competitive advantage.

The measurement of metabolic rates is important in many areas of science. Examples range from ecology through a broad spectrum of physiological disciplines to biomedical fields such as genetic screening, obesity, and trauma research. The organisms being measured range in size from bacteria through insects to whales, and many different measurement methodologies have developed over the years, most of which are famously difficult for the novice to master. This book covers a wide range of metabolic measurement techniques, giving background and applications information for each, with enough practical detail to allow for accurate and informed measurements with minimal trial-and-error. Much tribal wisdom, passed down from professors to students and between scientific peers, is included. A broad range of techniques is covered, including Gilson and Warburg respirometry and their modern derivatives; direct calorimetry; stable isotope work; coulometric respirometry; aquatic respirometry; and practically every variation of field and laboratory flow-through respirometry, including complex, computer-driven multi-animal systems. Characteristics of the different varieties of gas analyzers, flow measurement systems, and so on are evaluated in detail. The book brings to the task over two decades of experience in practically every type of respirometry, from laboratory settings to the jungles of Panama and the deserts of Namibia.

This book provides an overview of issues and techniques relevant to the development of cross-cultural measures and provides a step-by-step approach to the assessment of cross-cultural equivalence of measurement properties. The readers are introduced to an overview of the definitions of culture and a brief discussion of cross-cultural anthropology, psychology, sociology, and political science and the influences of these fields on social work. The book describes the process of cross-cultural instrument development, from formulating the research aims to the assessments of cross-cultural measurement properties. There are guides and recommendations for building a cross-cultural research support team for various critical tasks. The book addresses the issues of adopting and adapting existing research instruments. The processes and issues of cross-cultural translation and assessments are presented and discussed in detail. The book offers a discussion of the foundation of measurement theories and the entire process of instrument development from the definitions of abstract concepts, the construction of observed indicators, and assessment of the validity and reliability of the new instruments. The book demonstrates the application of item distribution analysis, internal consistency analysis, and exploratory factor analysis as a preliminary assessment of cross-cultural equivalence of research instruments. In addition, the book explains and illustrates the application of confirmatory factor analysis and multisample confirmatory factor analysis to evaluate the factor structure and testing of cross-cultural measurement invariance.

This book provides an overview of scale and test development. From conceptualization through design, data collection, analysis, and interpretation, critical concerns are identified and grounded in the increasingly sophisticated psychometric literature. Measurement within the health, social, and behavioral sciences is addressed, and technical and practical guidance is provided. Acknowledging the increasingly sophisticated contributions in social work, psychology, education, nursing, and medicine, the book balances condensation of complex conceptual challenges with focused recommendations for conceiving, planning, and implementing psychometric study. Primary points are carefully referenced and consistently illustrated to illuminate complicated or abstract principles. Basics of construct conceptualization and establishing evidence of validity are complimented with introductions to concept mapping and cross-cultural translation. In-depth discussion of cutting edge topics like bias and invariance in item responses is provided. Exploratory and confirmatory factor analytic strategies are illustrated and critiqued, and step-by-step guidance is offered for anticipating elements of a complete data collection instrument, determining sampling frame and size, and interpreting resulting coefficients. Much good work has been done by RAI developers to date. Too often, practitioners or researchers either underestimate the skills and effort required, or become overwhelmed by the complexities involved.

This book is a philosophical study of the nature and value of happiness. Part I is devoted to critical discussion of the most important theories about the nature of happiness, understood as some sort of psychological state. Views discussed include sensory hedonism, local preferentism, Kahneman's theory, and Whole Life Satisfactionism. Part II of the book contains the exposition and defense of a novel theory about the nature and value of happiness. It is a form of attitudinal hedonism. The idea that a person's welfare, or well‐being, depends essentially on happiness is explained and (with reservations) defended, provided that happiness is understood according to the theory presented here. Part III of the book extends the discussion into some areas that bear on interactions between empirical research concerning happiness and philosophical inquiry into the same phenomenon. Current methods of measuring happiness are criticized and a new method is proposed. Philosophical implications of empirical research concerning happiness are evaluated.

The accurate measurement of exposure to putative causes of disease is essential to the validity of epidemiologic research. This book covers general principles and methods that can be applied to accurately measure a wide range of exposures (risk factors) in epidemiology, including demographic, anthropometric, nutritional, medical, reproductive, genetic, metabolic, and environmental factors. It covers the methods and quality control approaches for the most commonly used data collection methods in epidemiology, including personal interviews, self administered questionnaires, abstraction of records, keeping of dairies, measurements in blood and other body products, and measurements of the environment. The emphasis is on general methods and examples, but not on detailed reviews of the measurement methods for specific exposures. This book also covers three other major topics relevant to exposure measurement. The first is methods to design, analyze, and interpret validity and reliability studies that quantify the degree of measurement error for a specific exposure. This topic is included because such ancillary studies are important in understanding the effects of exposure measurement error on the ‘parent’ epidemiologic study. The second is methods to maximize response rates. While this topic falls under the construct of reducing selection bias, and most of the rest of the book is focused on reducing misclassification bias, it is included because it is an important aspect of the data collection phase of most epidemiologic studies. The third additional topic, ethical issues in the conduct of epidemiologic research, is included for the same reason.

At least since the publication of Isaiah Berlin's famous essay ‘Two Concepts of Liberty’ nearly half a century ago, political philosophers have argued vigorously over the relative merits of ‘positive’ and ‘negative’ accounts of freedom. Matthew Kramer writes squarely within the negative-liberty tradition, but he incorporates a number of ideas that are quite often associated with theories of positive liberty. Much of The Quality of Freedom is devoted to elaborating the necessary and sufficient conditions for the existence of particular freedoms and unfreedoms; however, the book's cardinal objective is to establish the measurability of each person's overall freedom and of each society's aggregate freedom. On the one hand, Kramer contends that the existence of any particular instance of liberty or unfreedom is a matter of fact that can be confirmed or disconfirmed without any reliance on evaluative or normative considerations. On the other hand, he argues that the extent of each person's overall freedom or unfreedom cannot be ascertained entirely in the absence of evaluative assumptions. By combining those two positions and developing them in detail, Kramer pits himself against all positive accounts of liberty and most negative accounts. In the course of so doing, he aims to demonstrate the rigorous measurability of overall liberty – something that many writers on freedom have casually dismissed as impossible. Although Kramer concentrates principally on constructing a systematic analysis of socio-political freedom, he engages critically with the work of many of the leading contemporary writers on the topic.

Optics—a field of physics focusing on the study of light—is also central to many areas of biology, including vision, ecology, botany, animal behavior, neurobiology, and molecular biology. This book introduces the fundamentals of optics to biologists and nonphysicists, giving them the tools they need to successfully incorporate optical measurements and principles into their research. The book starts with the basics, describing the properties of light and the units and geometry of measurement. It then explores how light is created and propagates and how it interacts with matter, covering topics such as absorption, scattering, fluorescence, and polarization. The book also provides a tutorial on how to measure light as well as an informative discussion of quantum mechanics. The book features a host of examples drawn from nature and everyday life, and several appendixes that offer further practical guidance for researchers. This concise book uses a minimum of equations and jargon, explaining the basic physics of light in a succinct and lively manner. It is the essential primer for working biologists and for anyone seeking an accessible introduction to optics.
