Originally published in 1971. The three contributions collected in this volume deal with different aspects of a single theme—the logical status of scientific theories in their relation to observation. These lectures, authored by different thinkers, treat this theme in connection with some controversies in the philosophy of science. A nonspecialist who reads these lectures should realize that the theme itself is a perennial one with an ancient lineage. It has concerned philosophers from the earliest era of philosophy on down through the centuries. A central philosophical issue at stake in the lectures is the question of whether scientific theories are testable in terms of our observations such that we can know whether some theories are true and others false. Although differing in their emphases, all three contributors seek a more plausible and nonskeptical philosophical account of the status of scientific theories in relation to observation.

This 2001 book presents a general theory as well as a constructive methodology to solve 'observation problems', that is, reconstructing the full information about a dynamical process on the basis of partial observed data. A general methodology to control processes on the basis of the observations is also developed. Illustrative but also practical applications in the chemical and petroleum industries are shown. This book is intended for use by scientists in the areas of automatic control, mathematics, chemical engineering and physics.

One of the pathways by which the scientific community confirms the validity of a new scientific discovery is by repeating the research that produced it. When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science.

This edition of Science and Creationism summarizes key aspects of several of the most important lines of evidence supporting evolution. It describes some of the positions taken by advocates of creation science and presents an analysis of these claims. This document lays out for a broader audience the case against presenting religious concepts in science classes. The document covers the origin of the universe, Earth, and life; evidence supporting biological evolution; and human evolution. (Contains 31 references.) (CCM)

`This is an impressively detailed, clearly written book.... It is a book that I would like students to read′ - Clive Seale, Goldsmiths College, London Social Research: Theory, Methods and Techniques presents an understanding of social research practice through appreciation of its foundations and methods. Stretching from the philosophy of science to detailed descriptions of both qualitative and quantitative techniques, it illustrates not only `how′ to do social research, but also `why′ particular techniques are used today. The book is divided into three parts: Part One: Illustrates the two basic paradigms - quantitative and qualitative - of social research, describing their origins in philosophical thought and outlining their current interpretations. Part Two: Devoted to quantitative research, and discusses the relationship between theory and research practice. It also presents a discussion of key quantitative research techniques. Part Three: Examines qualitative research. Topics range from classical qualitative techniques such as participant observation, to more recent developments such as ethnomethodological studies. Overall, the author offers an engaging contribution to the field of social research and this book is a reminder of the solid foundations upon which most social research is conducted today. As a consequence it will be required reading for students throughout the social sciences, and at various levels.

Observing young children at play is an everyday and often fascinating and pleasurable experience for many of us. It also has a great pedigree in the development of psychoanalysis from Freud's observation of his grandson's game with the cotton-reel onwards. This book describes the practice of observing young children in home and nursery settings in a systematic and non-intrusive way in order to expand our understanding of their emotional, cognitive, and social development. It uses a psychoanalytic lens to enrich the meaning of what is seen. How do minds and personalities take shape? How can we train people to see what is most relevant in helping children to develop? The chapters range from classic papers by famous practitioners of an older generation to observations completed in recent years in the UK, Europe, and the US. Observation of this sort has also spread to Latin America, India, Australia, Africa, and the Far East. The differences and continuities with Infant Observation are the starting point.
