Testing

The advent of electronic computing permits the empirical analysis of economic models of far greater subtlety and rigour than before, when many interesting ideas were not followed up because the calculations involved made this impracticable. The estimation and testing of these more intricate models is usually based on the method of Maximum Likelihood, which is a well-established branch of mathematical statistics. Its use in econometrics has led to the development of a number of special techniques; the specific conditions of econometric research moreover demand certain changes in the interpretation of the basic argument. This book is a self-contained introduction to this field. It consists of three parts. The first deals with general features of Maximum Likelihood methods; the second with linear and nonlinear regression; and the third with discrete choice and related micro-economic models. Readers should already be familiar with elementary statistical theory, with applied econometric res

The technique of allometry investigates the effects of size on such variables as food intake, energy requirements, growth rates and age at first reproduction. This book brings together much of what is known about the consequences of size and provides a new and mathematically rigorous framework within which many quantitative predictions are made and tested using published and unpublished data. Explanations are proposed for many previously unexplained phenomena such as why in some species females are thousands of times heavier than males, whereas in no species are males more than about eight times heavier than females. The models presented afford a synthesis of the effects of size and open up pathways for further theoretical investigation and experimental testing. Care has been taken to give verbal presentations of all the mathematical conclusions to ensure that the text is widely intelligible.

Holographic and speckle interferometry are optical techniques which use lasers to make non-contracting field view measurements at a sensitivity of the wavelength of light on optically rough (i.e. non-mirrored) surfaces. They may be used to measure static or dynamic displacements, the shape of objects, and refractive index variations of transparent media. As such, these techniques have been applied to the solution of a wide range of problems in strain and vibrational analysis, non-destructive testing (NDT), component inspection and design analysis and fluid flow visualisation. This book provides a self-contained, unified, theoretical analysis of the basic principles and associated opto-electronic techniques (for example Electronic Speckle Pattern Interferometry). In addition, a detailed discussion of experimental design and practical application to the solution of physical problems is presented. In this new edition, the authors have taken the opportunity to include a much more coherent

The potato is one of the world's most important food crops. It produces more nutritious food from less land in a shorter time than any other major crop. Therefore advances in the production of new potato varieties will greatly contribute to the world's food supply. The book outlines strategies used in the breeding and testing of potato varieties. It considers prospects for varietal improvement using both traditional and new techniques, including genetic manipulation, tissue culture and protoplast fusion. Opportunities for breeding varieties suitable for propagation from true seed, of particular significance to the agricultural systems of developing countries, are also featured, together with an extensive and bibliography. The book is based on the proceedings of a joint meeting of EAPR and EUCARPIA at King's College, Cambridge, December 1985. It contains contributions from many leading authorities in potato breeding and variety assessment throughout the world, and will interest post-gra

First published in 1985, this book presents a 'triarchic' theory of human intelligence that goes beyond IQ in its conceptualisation and implications for assessment. The theory has three parts. The first deals with relations between intelligence and experience; the second, with relations between intelligence and the external world; the third part with relations between intelligence and the internal world of the individual. Robert J. Sternberg begins by sketching the history of intelligence research. He then outlines the three parts of the theory and adduces supporting evidence, including evidence from studies of 'practical' as well as 'academic' intelligence. He considers the issues raised by exceptional intelligence and by intelligence testing. His conclusions will be of interest to all those concerned with intelligence, its development and its measurement.

First published in 1979, this book examines past thought and research about the social and psychological causes of juvenile delinquency in Western society. The first few chapters summarise major delinquency theories and survey an extensive list of studies that demonstrate those theories. The author then develops a single model of individual causation from the divergent theoretical traditions. The model includes such variables as social class, parent-child relations, school experiences, strain, peer relations, personal values and the perceived risk of being caught in lawbreaking. Testing the model with information from 734 large-city adolescents results in several innovations in the measurement and conceptualisation of key variables in delinquency research. In his search for a better understanding of delinquency, the author shows the usefulness of examining the impact of all the variables at once and finds that the major theories of delinquency complement rather than contradict one anot

Many students of physical and applied science and of engineering find difficulty in copying with the mathematics necessary for the quantitative manipulation of the physical concepts they are atudying in their main course. This book is designed to help first and second year under-graduates at universities and polytechnics, as well as technical college students, to find their feet in the important mathematical methods they will need. Throughout the text the physical relevance of the mathematics is constantly stressed and, where it is helpful, use has been made of pictorial mathematics and qualitative verbal descriptions instead of over-compact mathematical symbolism. Topics are presented in three stages: a qualitative introduction, a more formal presentation and an explicit check or worked example. There are many exercises included in the text which are aimed at testing a student's understanding and building his confidence progressively throughout each piece of work.

The affluent workers studied in this book, originally published in 1968, were employees of three major industrial concerns sited in Luton at the time. The three firms were selected as being amongst Luton's best-paying employers and also on account of their advanced personnel and labour relations policies. This choice enabled comparisons to be made between workers engaged in very different types of production system. On the basis of material from interviews and other data, the authors examine in detail workers' experience of their industrial jobs, their relations with workmates, and the nature of their attachment both to the organizations which employ them and to their trade unions. This study forms part of a larger project which was aimed at testing empirically the thesis, which was most prevalent 1968, that of the progressive assimilation of manual workers and their families into the pattern of middle class social life.

A behind-the-scenes look at the dysfunction that contributed to the 2018 and 2019 crashes of the Boeing 737 MAX.Boeing is a century-old titan of industry. It played a major role in the early days of commercial flight, World War II bombing missions, and moon landings. But in 2018 and 2019, two crashes of the Boeing 737 MAX 8 killed 346 people, exposing a shocking pattern of malfeasance, leading to the biggest crisis in the company’s history―and one of the costliest corporate scandals ever. Flying Blind is the definitive exposé of the disasters that transfixed the world. Drawing from exclusive interviews with current and former employees of Boeing and the Federal Aviation Administration; industry executives and analysts; and family members of the victims, it reveals how a broken corporate culture paved the way for catastrophe. It shows how, in the race to beat the competition and reward top executives, Boeing skimped on testing, pressured employees to meet unrealistic deadlines, and co
