Book Description
Signal analysis and signal treatment are integral parts of all types of Nuclear Magnetic Resonance. In the last ten years, much has been achieved in the development of dimensional spectra. At the same time new NMR techniques such as NMR Imaging and multidimensional spectroscopy have appeared, requiring entirely new methods of signal analysis. Up until now, most NMR texts and reference books limited their presentation of signal processing to a short introduction to the principles of the Fourier Transform, signal convolution, apodisation and noise reduction. To understand the mathematics of the newer signal processing techniques, it was necessary to go back to the primary references in NMR, chemometrics and mathematics journals. The objective of this book is to fill this void by presenting, in a single volume, both the theory and applications of most of these new techniques to Time-Domain, Frequency-Domain and Space-Domain NMR signals. Details are provided on many of the algorithms used and a companion CD-ROM is also included which contains some of the computer programs, either as source code or in executable form. Although it is aimed primarily at NMR users in the medical, industrial and academic fields, it should also interest chemometricians and programmers working with other techniques.

Book Description
Thickening Fat: Fat Bodies, Intersectionality, and Social Justice seeks to explore the multiple, variable, and embodied experiences of fat oppression and fat activisms. Moving beyond an analysis of fat oppression as singular, this book will aim to unpack the volatility of fat—the mutability of fat embodiments as they correlate with other embodied subjectivities, and the threshold where fat begins to be reviled, celebrated, or amended. In addition, Thickening Fat explores the full range of intersectional and liminal analyses that push beyond the simple addition of two or more subjectivities, looking instead at the complex alchemy of layered and unstable markers of difference and privilege. Cognizant that the concept of intersectionality has been filled out in a plurality of ways, Thickening Fat poses critical questions around how to render analysis of fatness intersectional and to thicken up intersectionality, where intersectionality is attenuated to the shifting and composite and material dimensions to identity, rather than reduced to an “add difference and stir” approach. The chapters in this collection ask what happens when we operationalize intersectionality in fat scholarship and politics, and we position difference at the centre and start of inquiry.

Book Description
Major Problems in Developmental Biology contains the proceedings of the 25th Symposium of the Society for Developmental Biology, held in Haverford, Pennsylvania, in June 1966. The papers explore some of the major problems in developmental biology, particularly those relating to cell differentiation, movements, and death; patterning; and intercellular regulation in plants. Organized into 11 chapters, this book begins with an overview of the growth and development of developmental biology as a scientific discipline, with emphasis on the role of the Society for Developmental Biology, and in particular its symposia, in the emergence of the field. The book then discusses the intra- and extracellular factors impinging upon the nucleus and regulating cell differentiation. Some chapters focus on the dynamics of determination in cell systems of insects, morphogenetic movements of animal cells, and patterns at the cell and tissue levels. The reader is also introduced to the correlations between protein structure and function in relation to cell dynamics and differentiation, along with the physiological, biochemical, and molecular biological aspects of intercellular regulation in plants and the role of cell surface in carcinogenesis. The book concludes by suggesting directions for research into the ontogeny of behavior. This book is a valuable source of information for developmental biologists.

Book Description
This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.

Book Description
From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.

Book Description
This book was first published in French in 1994. It has been a training support to numerous researchers as well as practitioners, such as teachers, health workers, personal or sport trainers. Since then, it has constantly been republished and a glossary has been added in 1998. This version is the first complete edition of the book in English. The main idea of this new interview technique is to help a teacher, a supervisor or a researcher to guide the student, the practitioner or the subject to give a fine retrospective description of an action. As it is only the subject that has access to this mental or physical action, the goal is to help the subject with the verbalization, putting the implicit knowledge of this action in words. Yet, to achieve this verbalization, we need guidance, because we don't know how to give such a description ourselves. If we leave the interviewee without guidance, he risks remaining in the implicit, speaking in a general way, or in an incomplete or imprecise way, commenting instead of describing. The explicit and precise description we aim is the opposite of the implicit, meaning a fine, detailed and complete way of putting the action in words. The final aim is to elucidate what the subject did to seek his goal
