Spiders in Ecological Webs

Spiders in Ecological Webs

David H. Wise

Cambridge University Press
1995
pokkari
As experimental organisms, spiders offer ecologists a unique opportunity to examine the concept of the ecological community and the role which field experimentation can play in evaluating theories of population and community ecology. In this book, David Wise provides a balanced critique of field experiments designed to uncover details of spider ecology, with the dual aim of clarifying the ecology of these fascinating organisms and providing insight into the advantages and challenges of performing field experiments with a predator ubiquitous in terrestrial ecosystems. This book will be an essential reference for all ecologists wishing to learn more about the ecology of a major terrestrial predator and the use of field experimentation as a powerful technique to test ecological hypotheses.
Population Production and Regulation in the Sea

Population Production and Regulation in the Sea

David H. Cushing

Cambridge University Press
1995
sidottu
How do fish populations regulate themselves? Why do some fish stocks flourish and then die away? These questions have fascinated fisheries scientists for decades, and in the last twenty years answers have begun to emerge. In this comprehensive account, David Cushing shows how the fate of fish larvae which live close to the centres of production in the sea has a crucial effect on population regulation. He shows how the timing and development of tidal fronts in particular regions has profound implications for fish and plankton production, which in turn affects fish recruitment. If recruitment of fish larvae into the pool of adult fish is insufficient, stocks may fail. It is only by understanding these processes that we can hope to recognise the implications of global climate change on marine populations. This book will be essential reading for all those interested in marine ecology and fisheries biology.
Development of Mature Walking

Development of Mature Walking

David H. Sutherland; Richard A. (CON) Olshen

Cambridge University Press
1991
sidottu
This important monograph summarizes a comprehensive study on the maturation of walking in normal children. Research, undertaken at one of the world's leading gait analysis centers, involved over 400 studies on a total of nearly 300 children in ten age-groups from one to seven years. Data are presented on anthropometric measurements; tests of developmental progress; time/distance parameters such as stride length and walking velocity; twelve joint angles on each side measured throughout the gait cycle; dynamic electromyography of phasic activity in seven lower-extremity muscle groups; and force measurements including vertical force, fore/aft shear, medial/lateral shear and torque. At each age, composite joint-angle graphs and time/distance parameters are brought together with film tracings of a representative child in that age group. In addition, advanced methods of statistical analysis have been applied to the joint-angle data to define prediction regions within which ninety-five percent of normal children should lie throughout the gait cycle.Finally, a 'decision tree' is presented from which a fitted age can be inferred for a subject based on non-age-specific data gathered in a motion analysis lab. Practical applications are demonstrated in a chapter devoted to two case studies.
Bromeliaceae

Bromeliaceae

David H. Benzing

Cambridge University Press
2000
sidottu
This book presents a synthesis of the extensive information available on the biology of Bromeliacea, a largely neotropical family of about 2700 described species. Reproductive and vegetative structure and related physiology, ecology and evolution are emphasized, rather than floristics and taxonomy. Guiding questions include: why is this family inordinately successful in arboreal (epiphytic) and other typically stressful habitats and also so important to extensive fauna beyond pollinators and frugivores in the forest canopy? Extraordinary and sometimes novel mechanisms that mediate water balance, tolerance for high and low exposures, and mutualisms with ants have received much study and allow interesting comparisons among plant taxa and help explain why members of this taxon exhibit more adaptive and ecological variety than most other families of flowering plants. This volume concentrates on function and underlying mechanisms, thus will round out a literature that otherwise mostly ignores basic biology in favour of taxonomy and horticulture.
Blindness and Children

Blindness and Children

David H. Warren

Cambridge University Press
1994
sidottu
The book is a summary and interpretation of the research literature on infants and children with visual impairments. It concludes that many aspects of ‘delayed’ development are not the result of visual impairment itself, but rather of environmental variables that tend to accompany visual impairment. Thus many of the typical developmental delays may be ameliorated or avoided by the appropriate structuring of the child’s experiences. The book is developmentally oriented and treats all of the major areas of child development. The author makes the premise that a truly useful body of knowledge about the development of children with visual impairments must not just characterize normative development, but must account for the factors that are associated with relatively good or poor developmental progress. Existing research literature is searched for evidence of variables that may account for individual differences, particularly variables related to the child’s several environments.

Observing Variable Stars

Observing Variable Stars

David H. Levy; Janet A. Mattei

Cambridge University Press
1998
pokkari
David Levy’s entertaining, well-researched book is aimed at the amateur enthusiast who likes to learn enjoyably. Beginning with advice on binoculars and telescopes, and how to observe the night sky effectively, the author goes on to describe thoroughly the field of variable star observation, a field in which amateurs have made important contributions. He shows how to interpret variations in light output in terms of the life of a star, from birth through to sometimes violent death. All of the major variable stars are described and classified, as well as other variable objects such as active galaxies, asteroids, comets and the sun. The book also contains a guide to the seasonal night sky. Throughout, practical observations serve to complement the text, producing an exciting, very readable introduction to this fascinating subject.
Between Politics and Science

Between Politics and Science

David H. Guston

Cambridge University Press
2000
sidottu
This book combines political-economic, sociological and historical approaches to provide a coherent new framework for analyzing the changing relationship between politics and science in the United States. Fundamental to this relationship are problems of delegation, especially the integrity and productivity of sponsored research: politicians must see that research is conducted with integrity and productivity, and scientists must be able to show it. A science policy regime changes when solutions to these problems change. After World War II, the ‘social contract for science’ assumed that the integrity and productivity of research were automatic and, despite many challenges, that contract endured for four decades. But in the 1980s, as rich empirical studies show, cases of misconduct in science and flagging economic performance broke the trust between politics and science. New ‘boundary organizations’, in which scientists and nonscientists collaborate to assure the integrity and productivity of research, were created to mend the relationship.
Nutritional Strategies for the Very Low Birthweight Infant

Nutritional Strategies for the Very Low Birthweight Infant

David H. Adamkin

Cambridge University Press
2009
pokkari
The goal of nutritional management in VLBW and ELBW infants is the achievement of postnatal growth at a rate that approximates the intrauterine growth of a normal fetus at the same postconceptional age. In reality, however, growth lags considerably after birth; although non-nutritional factors are involved, nutrient deficiencies are critical in explaining delayed growth. This practical clinically-oriented pocketbook reviews and summarises all available clinical evidence. It enables the reader to implement parenteral or enteral feeding plans, with the goals of reducing postnatal weight loss, earlier return to birthweight, and improved catch-up growth. Both nutrient balance and growth and the impact on neurodevelopment and health outcomes are evaluated. With many tables and algorithms to summarise key data and management strategies, Nutritional Strategies for the Very Low Birthweight Infant is an invaluable guide for all healthcare professionals caring for premature babies.
The Primordial Density Perturbation

The Primordial Density Perturbation

David H. Lyth; Andrew R. Liddle

Cambridge University Press
2009
sidottu
The origin and evolution of the primordial perturbation is the key to understanding structure formation in the earliest stages of the Universe. It carries clues to the types of physical phenomena active in that extreme high-density environment. Through its evolution, generating first the observed cosmic microwave background anisotropies and later the distribution of galaxies and dark matter in the Universe, it probes the properties and dynamics of the present Universe. This graduate-level textbook gives a thorough account of theoretical cosmology and perturbations in the early Universe, describing their observational consequences and showing how to relate such observations to primordial physical processes, particularly cosmological inflation. With ambitious observational programmes complementing ever-increasing sophistication in theoretical modelling, cosmological studies will remain at the cutting edge of astrophysical studies for the foreseeable future.
Etched in Stone

Etched in Stone

David H. Aaron

T. T.Clark Ltd

The document known as The Ten Commandments, more formally referred to as The Decalogue, remains among the most controversial and complicated passages in the Hebrew Bible. Even today, the twentieth chapter of Exodus continues to serve as a major religious and ethical icon within popular culture and religious communities, despite its many unexplained elements. Lawsuits over the display of Decalogue Tablets have occupied courtrooms in more than half the states of this country. And yet, few people understand that there is not one, but three versions of what are usually called The Ten Commandments. Moreover, when their ideological underpinnings are examined closely, these versions prove to be quite antithetical to one another. Even fewer are aware of the probability that these documents were written very late in the history of biblical literature - indeed, so late as to constitute a literary afterthought in the development of Israelite ethnic self-definition. In "Etched in Stone: The Emergence of the Decalogue Tradition", Aaron examines the question of when the Decalogue versions were written and why. The main focus of this book is the literary phenomenon known as 'the tablets' and how it functioned within the broader narrative. Aaron argues not only that the inclusion of the Decalogue texts was quite late in the development of the Pentateuch's canon, but that their integration preserves vestiges of highly charged ideological conflicts that were inadvertently neutralized by the rather bland and generic ethical precepts coined among its verses. "Etched in Stone" provides a paradigm for merging a variety of critical methods (source criticism, tradition criticism, ideological criticism, redaction criticism) and literary approaches that have heretofore been under-explored. In this sense, "Etched in Stone" will be read by scholars for its far-reaching conclusions and used by students (undergraduates, seminary, graduate) for learning approaches to the sequencing of biblical materials.
Coins as Cultural Texts in the World of the New Testament
Coins have long been a vital part of the discipline of classical studies of the ancient world. However, many scholars have commented that coins have not been adequately integrated into the study of the New Testament. This book provides an interdisciplinary gateway to the study of numismatics for those who are engaged in biblical studies. Wenkel argues that coins from the 1st century were cultural texts with communicative power. He establishes a simple yet comprehensive hermeneutic that defines coins as cultural texts and explains how they might be interpreted today. Once coins are understood to be cultural texts, Wenkel proceeds to explain how these texts can be approached from three angles. First, the world in front of the coin is defined as the audience who initially read and responded to coins as cultural texts. The entire Roman Empire used coins for payment. Second, the world of the coin refers to the coin itself – the combination of inscriptions and images. This combination of inscription and image was used ubiquitously as a tool of propaganda. Third, the world behind the coin refers to the world of power and production behind the coins. This third angle explores the concept of authorship of coins as cultural texts.
