    Abstract: When assuming the task of preparing a book such as this, one inevitably wonders why anyone would want to read it. I have always sympathized with Charles Elton's trenchant observation in his 1927 book that 'we have to face the fact that while ecological work is fascinating to do, it is unbearably dull to read about . . . ' And yet several good reasons do exist for producing a small volume on predation. The subject is interesting in its own right; no ecologist can deny that predation is one of the basic processes in the natural world. And the logical roots for much currently published reasoning about predation are remarkably well hidden; if one must do research on the subject, it helps not to be forced to start from first principles. A student facing predator-prey interactions for the first time is confronted with an amazingly diverse and sometimes inaccessible literature, with a ratio of wheat to chaff not exceeding 1: 5. A guide to the perplexed in this field does not exist at present, and I hope the book will serve that function. But apart from these more-or-Iess academic reasons for writing the book, I am forced to it by my conviction that predators are important in the ecological scheme. They playa critical role in the biological control of insects and other pests and are therefore of immediate economic concern.

    Abstract: The success of the book Soils and the Environment imagination in the applications of soil surveys, illustrates the need for further, more detailed toward the end of improving productivity and information about soil survey interpretations (uses efficiency in the use of soils and the environment. of soil surveys), especially for laypersons, teachers, Although laypersons, teachers, and students are the and students. Much information about soils and primary groups addressed by this Field Guide, the environment is secluded in offices of various other people involved with using soil surveys are agencies and institutions and thus is not readily (or will be) agriculturalists, agronomists, assessors, available to the people who need it. Techniques for botanists, conservationists, contractors, ecologists, finding and using the information are also not well economists, engineers, extension workers, fores­ known, so there is great need for this Field Guide ters, geologists, groundwater experts, planners, to Soils and the Environment to provide teachers politicians, public health officials, range managers, and learners with exercises that will give them recreationists, soil scientists, wildlife specialists, and many others. This Field Guide complements practice leading to confidence in the manipulation and enhances the book Soils and the Environment and utilization of soil survey data. In a sense, all published in 1981. of us are (or should be) learners and teachers in the use of soil survey information. This Field Guide DONALD R.

    Abstract: This volume discusses the mineral resources upon which modern civiliza­ tion is built. Take away these minerals and humanity will rapidly return to the stone age, with its greatest concern the depletion of flint (also a mineral). It would, of course, result in about a 99% reduction in population. In other words, approximately 99% of the worlds' population is dependent on minerals for its existence. That is a pretty strong statement, but how many have even seen a travois? Without minerals, pack animals, rafts, rowboats, sail boats, sledges, and the backs of man would be the only forms of transport. Sufficient food could not be transported, nor could it be grown on our tired soils without tractors and fertilizer. Even in the more fertile tropics where nearly half of the population is now suffering from malnutrition, crops are dependent on "miracle" grains that require mechanization and mineral fertilizers. Modern buildings cannot operate without electricity and, without mineral fuels, few people in the northern latitudes would survive the first winter.

    Abstract: The first edition of this book was received more kindly than it deserved by some, and with some scepticism by others. It set out to present a simple, concise and reasonably comprehensive introduction to some of the theoretical and empirical criteria which may be used to define rock as a structural material. The objectives - reinforced by the change in title - remain the same, but the approach has been changed considerably and only one or two sections have been retained from the first edition. The particular aim in this edition is to provide a description of the mechanical behaviour of rocks, based firmly upon experimental data, which can be used to explain how rocks deform, fracture and yield, and to show how this knowledge can be used in design. The major emphasis is on the behaviour of rocks as materials, although in the later chapters the behaviour of discontinuities in rocks, and the way in which this can affect the behaviour of rock masses, is considered. If this edition is an improvement on the first edition it reflects the debt lowe to numerous people who have attempted to explain the rudiments of the subject to me. I should like to thank Peter Attewell and Roy Scott in particular. I should also like to thank Tony Price and Mike Gilbert whose work at Newcastle I have used shamelessly.

    Abstract: In this small book I have tried to confine myself to the absolute necessities in a field which requires a knowledge of both biology and physics. It is meant as a primer for biological undergraduates. I hope it will lead some of them to further, more advanced, study. It has not been easy to present the subject in so few pages, and I am aware of many omissions. I hope readers will agree that it is best to concentrate on a small number of topics, which together constitute an essay on plant-atmosphere relationships. Advanced students will be able to take the subject further if they look up some of the references. Text books that I particularly recommend are those by Monteith [38] and Campbell [lOO]. If the reader intends to carry out research investigations he should also consult Fritschen and Lloyd [105] for an introduction to instrumentation in environmental biophysics.

    Abstract: Katherine Teilmann Van Dusen and Sarnoff A. Mednick This introduction delineates what we consider to be three of the most important impediments to the advance of knowledge in the field of criminology. The most fundamental need is for more studies of the nature and progress of criminal and delinquent careers. The second need is for more prospective, longitudinal studies of the etiology of crime and delinquency. The third need concerns the lack of interdisciplinary research toward a more integrated understanding of delinquent and criminal behavior. Criminal and Delinquent Careers The birth cohort study by Wolfgang, Figlio and Sellin (1972) was heralded by many (Farrington, 1973; Erickson, 1973; Weis, 1974) as a landmark which allowed researchers to study the course of delinquency without the usual sampling biases that plagued other, cross-sectional research. For the first time, we could get a reasonable picture of when delinquency usually starts, what proportion of the population engages in delinquency, what types of delinquencies they engage in, what proportion continue, and so on. Cross sectional studies do not permit the investigation of careers because cross 1 PROSPECTIVE STUDIES OF CRIME AND DELINQUENCY 2 sectional sampling includes only portions of careers for many of the individuals sampled. This is just one of the many problems that restricted researchers' ability to study the nature of criminal careers.

    Abstract: As we enter the last decades of the twentieth century, many persistent and perplexing problems continue to afflict humankind. Thus it is appropriate to address, in a new group of books, two of the monumental issues that haunt people throughout the world. Soils and the Environment by Professor Gerald W. Olson is the first book in this new publish­ ing program on Environment, Energy, and Society. The purpose of all these books will be to explore the many interrelated facets of these topics and to provide guidance for deal ing with problems and offering ideas for their solutions. Environment and energy are twin problems that occupy what many believe to be opposite sides of a two-headed coin. They are often viewed as being antithetical and incompatible. The various books in this program will try to place in perspective the options that are available to those who design policy and plan and manage societal matters. Typical of books being developed currently are ones on coal resources, environmental geoscience, environmental pollution, land-use planning, nuclear energy, mineral resources, and water resources. However, because soils are at the very heart of civilization and provide the building block for human sustenance, it is fitting to inaugurate this series with Dr. Olson's timely analysis of soils. Unfortu­ nately, these most vital resources seen. to have low priority in many farming enterprises, urbanization projects, deforestation schemes, and mining and developmental terrain changes.

    Abstract: The student of biolo,gical science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a background knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in sufficient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook of biology. This outline then sets out to provide by building on this basis, the conceptual framework within which modern research work is progressing and aims to give the reader an indication of the problems, both conceptual and practical, which must be overcome if progress is to be maintained.

    Abstract: In the past two decades there has been an increasing public awareness of the hazards that exist from the contamination of the environment by toxic substances. 'Heavy metals' and the terrestrial environment are but one facet of the impact of toxic substances on the natural environment, and the use of biological materials for indicating the occurrence of, and continually monitoring the presence of, these materials is a specific topic which is of considerable interest to a diverse range of individuals, organisations and disciplines. It was our intention when we first en­ visaged this book that it should contain a description of a range of circumstances in which biological monitoring techniques have been employed in the terrestrial environment and that it should be seen as a practical text which dealt with the merits, shortcomings and suitability of biological monitoring materials. Monitoring is, however, a manifold process. It serves not only to provide information on past and present concentrations of toxic materials in various components of the environ­ ment, but also to provide information on the processes of environmental release, transport, accumulation and toxicity. Indeed, this may be one of the greatest virtues of biological monitoring over other forms of monitor­ ing. According to the skill of the staff employed in the monitoring procedure, the information that is accrued can have a vastly different value.

    Abstract: Joseph F. White has studied, worked, and taught in all aspects of microwave semiconductor materials, control diodes, and circuit applications. He is thoroughly grounded in the physics and math­ ematics of the field, but has primarily the engineer's viewpoint, combining basic knowledge with experience and ingenuity to gen­ erate practical designs under constraints of required performance and costs of development and production. As a result of his teach­ ing experience and numerous technical papers and oral presenta­ tions, he has developed a clear, well-organized writing style that makes this book easy to use as a self-teaching text, a reference volume, and a design handbook. Dr. White believes that an engineer must have a good understand­ ing of semiconductor physics, a thorough knowledge of microwave circuit theory, at least an elementary acquaintance with transistor drivers, and the ability to check and refine a microwave circuit on a computer terminal to be qualified for modern, creative design of microwave semiconductor control components. These subjects are well covered in approximately the first half of the book; the second half treats the general and specific design of switches, at­ tenuators, limiters, duplexers, and phase shifters, with many ex­ amples drawn from his experience and that of others.

    Abstract: Often the meanings of words are changed subtly for interesting reasons. The implication of the word 'community' has changed from including all the organisms in an area to only those species at a particular trophic level (and often a taxonomically restricted group), for example, 'bird-community'. If this observation is correct, its probable cause is the dramatic growth in our knowledge of the ecological patterns along trophic levels (I call these horizontal patterns) and the processes that generate them. This book deals with vertical patterns - those across trophic levels -and tries to compensate for their relative neglect. In cataloging a dozen vertical patterns I hope to convince the reader that species interactions across trophic levels are as patterned as those along trophic levels and demand explanations equally forcefully. But this is not the only objective. A limited number of processes shape the patterns of species interaction; to demonstrate their existence is an essential step in understanding why ecosystems are the way they are. To achieve these aims I must resort to both mathematical techniques to develop theories and statistical techniques to decide between rival hypotheses. The level of mathematics is likely to offend nearly everyone. Some will find any mathematics too much, while others will consider the material to be old, familiar ground and probably explained with a poor regard for rigour and generality.

    Abstract: Many chemists and biochemists require to know the ionization constants of organic acids and bases. This is evident from the Science Citation Index which lists The Determination of Ionization Constants by A. Albert and E. P. Serjeant (1971) as one of the most widely quoted books in the chemical literature. Although, ultimately, there is no satisfactory alternative to experimental measurement, it is not always convenient or practicable to make the necessary measure­ ments and calculations. Moreover, the massive pK. compilations currently available provide values for only a small fraction of known or possible acids or bases. For example, the compilations listed in Section 1. 3 give pK. data for some 6 000--8 000 acids, whereas if the conservative estimate is made that there are one hundred different substituent groups available to substitute in the benzene ring of benzoic acid, approximately five million tri-substituted benzoic acids are theoretically possible. Thus we have long felt that it is useful to consider methods by which a pK. value might be predicted as an interim value to within several tenths of a pH unit using arguments based on linear free energy relationships, by analogy, by extrapolation, by interpolation from existing data, or in some other way. This degree of precision may be adequate for many purposes such as the recording of spectra of pure species (as anion, neutral molecule or cation), for selection of conditions favourable to solvent extraction, and for the interpretation of pH-profiles for organic reactions.

    Abstract: The Photoelectric Spectrometry Group was formed in July 1948 in Cambridge. The Group was born out of a need for a forum of users to discuss problems and methodology associated with the new era of photoelectric spectrometers. Over the years the aims and objectives of the Group have been broadened to include many aspects of ultraviolet and visible spectrometry. In 1973, the Group renamed itself the UV Spectrometry Group (UVSG). The techniques of fluorescence, diffuse reflectance, ORD and CD were included in the Group's interest. In 1979, the UVSG became a registered charity. The present Group membership is some 200 practising spectroscopists, mostly from the UK with a small but growing overseas membership. In August 1977, the UVSG Committee set up three Working Parties: Cells for UV-Visible Spectrophotometers; Photometric and Wavelength Standards; and the Calibration of Fluorimeters. It was felt that a wealth of information and expertise in the practice of spectrometry was available within the Group and that it was appropriate for this to be gathered together in the form of a number of monographs. Initially the intention was that these should be circulated only amongst the Group membership. However, the suggestion was made that these monographs would be of interest to other scientists outside our specialist Group. The conclusions of the first two Working Parties were combined in Volume 1 of this series, and this monograph summarizes the work of the third Working Party.

    Abstract: Throughout the history of warfare at sea, navigation has been an important basic determinant of victory. Occasionally, new members of the fraternity of the sea will look upon navigation as a chore to be tolerated only as long as it takes to find someone else to assume the responsibility. In my experience, such individuals never make good naval officers. Commander Hobbs has succeeded in bringing together the information and practical skills required for that individual who would take the first step down the road toward becoming a competent marine navigator. At the outset of this book, the author stresses the necessity for safe navigation, but there is another basic tenet of sea warfare that this book serves. The best weapons system man has ever devised cannot function effectively unless it knows where it is in relation to the real world, where it is in relation to the enemy, and where the enemy is in relation to the real world. Not all defeats can be attributed to this lack of information, but no victories have been won by those who did not know where they were.

    Abstract: 1 Chemistry and Biochemistry of Trace Metals in Biological Systems -- 2 Lead: Understanding the Minimal Toxicity of Lead in Plants -- 3 Cadmium -- 4 Copper -- 5 Zinc -- 6 Nickel -- 7 Other Trace Metals -- 8 Metalloids.
    Abstract: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.

    Abstract: This book consists of a collection of essays written between 1965 and 1981. Some have been published elsewhere; others appear here for the first time. Although dealing with different figures and different periods, they have a common theme: all are concerned with examining how the method of hy­ pothesis came to be the ruling orthodoxy in the philosophy of science and the quasi-official methodology of the scientific community. It might have been otherwise. Barely three centuries ago, hypothetico­ deduction was in both disfavor and disarray. Numerous rival methods for scientific inquiry - including eliminative and enumerative induction, analogy and derivation from first principles - were widely touted. The method of hypothesis, known since antiquity, found few proponents between 1700 and 1850. During the last century, of course, that ordering has been inverted and - despite an almost universal acknowledgement of its weaknesses - the method of hypothesis (usually under such descriptions as 'hypothetico­ deduction' or 'conjectures and refutations') has become the orthodoxy of the 20th century. Behind the waxing and waning of the method of hypothesis, embedded within the vicissitudes of its fortunes, there is a fascinating story to be told. It is a story that forms an integral part of modern science and its philosophy.

    Abstract: The student of biological science in his final years as an undergraduate and his first years as a graduate is expected to gain some familiarity with current research at the frontiers of his discipline. New research work is published in a perplexing diversity of publications and is inevitably concerned with the minutiae of the subject. The sheer number of research journals and papers also causes confusion and difficulties of assimilation. Review articles usually presuppose a back­ ground knowledge of the field and are inevitably rather restricted in scope. There is thus a need for short but authoritative introductions to those areas of modern biological research which are either not dealt with in standard introductory textbooks or are not dealt with in suffi­ cient detail to enable the student to go on from them to read scholarly reviews with profit. This series of books is designed to satisfy this need. The authors have been asked to produce a brief outline of their subject assuming that their readers will have read and remembered much of a standard introductory textbook on biology. This outline then sets out to provide by building on this basis, the conceptual framework within which modern research work is progressing and aims to give the reader an indication of the problems, both conceptual and practical, which must be overcome if progress is to be maintained.

    Abstract: This volume in the Energy from Wastes Series covers the area of methane production from agricultural and domestic wastes. Principally this involves the conversion of excreta and other organic effluents to a valuable gaseous fuel plus, in many cases, a useful sludge for fertiliser or feedstuffs. Dr Hobson and his colleagues have written a comprehensive text on the principles of microbiological processes and the biochemistry of anaerobic digestion, embracing the design of digesters with examples of current working installations. The potential for anaerobic digestion of wastes as diverse as sewage to fruit processing effluents is also reviewed. This work should be of interest to all who have to manage organic waste treatment and disposal, as well as to a wider readership who wish to know more about methane production by anaerobic digestion. ANDREW PORTEOUS v Preface The production of methane, or more exactly, a flammable 'biogas' containing methane and carbon dioxide, by microbiological methods ('anaerobic digestion') is not new. The reactions have been in industrial use for over a hundred years, but only in sewage purification processes. In some times of national stress, such as war-time, the microbiological production of gas purely for fuel has been investigated, but with the resumption of plentiful su pplies of fossil fuels the investigations have faded awa y.

    Abstract: "If a science has to be supported by fraudulent means, let it perish. " With these words of Kepler, Agassi plunges into the actual troubles and glories of science (321). The SOciology of science is no foreign intruder upon scientific knowledge in these essays, for we see clearly how Agassi transforms the tired internalistJexternalist debate about the causal influences in the history of science. The social character of the entire intertwined epistemological and practical natures of the sciences is intrinsic to science and itself split: the internal sociology within science, the external sociology of the social setting without. Agassi sees these social matters in the small as well as the large: from the details of scientific communication, changing publishing as he thinks to 'on-demand' centralism with less waste (Ch. 12), to the colossal tension of romanticism and rationality in the sweep of historical cultures. Agassi is a moral and political philosopher of science, defending, dis­ turbing, comprehending, criticizing. For him, science in a society requires confrontation, again and again, with issues of autonomy vs. legitimation as the central problem of democracy. And furthermore, devotion to science, pace Popper, Polanyi, and Weber, carries preoccupational dangers: Popper's elitist rooting out of 'pseudo-science', Weber's hard-working obsessive . com­ mitment to science. See Agassi's Weberian gloss on the social psychology of science in his provocative 'picture of the scientist as maniac' (437).

    Abstract: One facet of development in this field is that the methods of gathering and processing geophysical data, and displaying results, lead to presentations which are more and more comprehensible geologically. Expressed in another way, the work of the interpreter becomes progressively less onerous. The contributions in this collection of original papers illustrate this direction of development, especially in seismic prospecting. If one could carry out to perfection the steps of spiking deconvolution, migration and time--depth conversion, then the seismic section would be as significant geologically as a cliff-face, and as easy to understand. Perhaps this is not yet achieved, but it remains an objective, brought closer by work such as that described by the authors. The editor offers his best thanks to the contributors-busy geophysicists who have written with erudition on this range of subjects of current interest. A. A.

    Abstract: Writing this second edition of Biochemical Genetics proved to be more difficult than I had anticipated. The fixed format of the series meant that the addition of new material was made possible only by the dele­ tion of old. Since the book is intended for a student audience, I have retained the historical approach of the first edition and added new material only when it demonstrates a principle more effectively. At the time of writing, we are witnessing an information explosion resulting from the application of recombinant DNA technology to all manner of problems. I have added a sixth chapter indicating the impact of this work on our concepts of gene structure. I should like to thank Ed Byard, Bill Evans, Charles Schorn and Ed Ward, colleagues in the Biology Department at the University of Winnipeg, and Andrew Spence, a student in the department, for their comments on the manuscript of the second edition, and to reiterate my thanks to all those in the Department of Genetics at the University of Sheffield who commented on the first edition.

    Abstract: 1. Copolymer Characterisation by 13C NMR -- Semi-Crystalline Polymers by Neutron Scattering -- 3. Laser Raman Spectroscopy on Synthetic Polymers -- 4. Characterisation of Polymers by ESCA -- 5. Characterisation of Polymer Solutions and Melts by Acoustic Techniques -- 6. Flow Birefringence and the Kerr Effect.
    Abstract: The policy adopted in Volume 1 of this series of including a relatively small number of topics for detailed review has been continued here. The techniques selected have received considerable attention in recent years. F or this reason and because of the significance of the characterisation data, further coverage of 13C nuclear magnetic resonance spectroscopy and small angle neutron scattering is given in the first two chapters. In Chapter I a large part of the review describes the determination of monomer sequence distributions and configurational sequences in copolymers formed from more than one polymerisable monomer. The review on neutron scattering (Chapter 2) is directed towards the determination of the chain conformation in semi-crystaIIine polymers, which has provided important results for the interpretation of chain folding and morphology in crystaIIisable polymers. Laser Raman spectroscopy has also been used for morphological studies, and this application together with a description of the theoretical and experimental aspects of the technique is given in Chapter 3. X-ray photoelectron spectroscopy because of its extreme sensitivity to surface characteristics has provided information on polymeric solids that could not be obtained by other techniques. The principles and practice of this ESCA technique, including its use for simple elemental analysis, structural elucidation and depth profiling, are described in Chapter 4. The final two chapters are mainly concerned with the chain conformation of polymers in dilute solution. Ultrasonic techniques (Chapter 5) show pmmise for observing the dynamics of conformational changes.

    Abstract: 1 Introduction -- 2 Structural aspects of isoenzymes -- 3 Isoenzymes in genetics and evolution -- 4 Isoenzymes in development and differentiation -- 5 Isoenzymes in metabolic regulation -- 6 Isoenzymes in cancer -- 7 Isoenzymes in diagnosis and disease -- 8 Separation and determination of isoenzymes.
    Abstract: Isoenzymes were 'discovered' 20 years ago and were at first regarded as interesting but rare occurrences. Since then a wealth of information on enzyme heterogeneity has accrued and it now seems likely that at least half of all enzymes exist as isoenzymes. This is important in many areas of biological and medical science. Thus isoenzyme studies have provided the main experimental substance for the neutral drift controversy in genetics and evolution; they have greatly extended our understanding of metabolic regulation not only in animals but also in bacteria and plants; their existence has made available a multitude of highly sensitive markers for the study of differentiation and development, as well as providing indices of aberrant gene expression in carcinogenesis and other pathological processes. Iso­ enzymes are also being used increasingly in diagnostic clinical bio­ chemistry. It is surprising that this phenomenon which affects such a high pro­ portion of enzymes and is clearly important in biochemistry should receive such scant attention in the standard textbooks of that subject, the formal treatment of isoenzymology in these rarely exceeding one or two pages. This may be because the 'pure biochemist' has tended to regard variation in enzyme properties between tissues more as an unwanted complication than as a potential source of insight into diversity of biological function.

    Abstract: The emergence of Mossbauer spectroscopy as an important experi­ mental technique for the study of solids has resulted in a wide range of applications in chemistry, physics, metallurgy and biophysics. This book is intended to summarize the elementary principles of the technique at a level appropriate to the advanced student or experienced chemist requiring a moderately comprehensive but basically non-mathematical introduction. Thus the major part of the book is concerned with the practical applications of Mossbauer spectroscopy, using carefully selected examples to illustrate the concepts. The references cited and the bibliography are intended to provide a bridge to the main literature for those who subseouent­ ly require a deeper knowledge. The text is complementary to the longer research monograph, 'Mossbauer Spectroscopy', which was written a few years ago in co-authorship with Professor N.N. Greenwood, and to whom I am deeply indebted for reading the preliminary draft of the present volume. I also wish to thank my many colleagues over the past ten years, and in particular Dr. R. Greatrex, for the many stimu­ lating discussions which we have had together. However my greatest debt is to my wife, who not only had to tolerate my eccen­ tricities during the gestation period, but being a chemist herself was also able to provide much useful criticism of the penultima te draft.
