Robert May – författare

Robert May''s seminal book has played a central role in the development of ecological science. Originally published in 1976, this influential text has overseen the transition of ecology from an observational and descriptive subject to one with a solid conceptual core. Indeed, it is a testament to its influence that a great deal of the novel material presented in the earlier editions has now been incorporated into standard undergraduate textbooks. It is now a quarterof a century since the publication of the second edition, and a thorough revision is timely.Theoretical Ecology provides a succinct, up-to-date overview of the field set in the context of applications, thereby bridging the traditional division of theory and practice. It describes the recent advances in our understanding of how interacting populations of plants and animals change over time and space, in response to natural or human-created disturbance. In an integrated way, initial chapters give an account of the basic principles governing the structure, function, and temporal andspatial dynamics of populations and communities of plants and animals. Later chapters outline applications of these ideas to practical issues including fisheries, infectious diseases, tomorrow''s food supplies, climate change, and conservation biology. Throughout the book, emphasis is placed on questionswhich as yet remain unanswered.The editors have invited the top scientists in the field to collaborate with the next generation of theoretical ecologists. The result is an accessible, advanced textbook suitable for senior undergraduate and graduate level students as well as researchers in the fields of ecology, mathematical biology, environment and resources management. It will also be of interest to the general reader seeking a better understanding of a range of global environmental problems.

. . . a welcome addition . . . Psychoanalytic Psychotherapy in a College Context is a concise, erudite, and useful introduction to this emerging specialty. Contemporary Psychology An excellent addition to the sparse literature on psychotherapy in college settings. This well-written collection demonstrates the applicability and usefulness of brief psychoanalytic psychotherapy in college settings. It also usefully presents important information about some of the most difficult and demanding disorders treated in academic settings (e.g., eating and narcissistic character disorders). ChoiceIn one of the few professional books to consider psychotherapy with college students as a particular specialty, Robert May invited senior, experienced college psychotherapists to examine the unique and typical characteristics of therapy with young adults in college. From organizational and administrative aspects to specific clinical techniques, Psychoanalytic Psychotherapy in a College Context offers college counselors, clinical psychologists, psychiatrists, and psychoanalysts all the information needed for effective, sound treatment.

In comparative syntax a general approach has been pursued over the past decade predicated on the notion that Universal Grammar allows of open parameters, and that part of the job of linguistic theory is to specify what values these parameters may have, and how they may be set, given primary linguistic data, to determine the grammars of particu­ lar languages. The papers presented in this volume are also concerned with language variation understood in this way. Their goals, however, do not strictly fall under the rubric of comparative syntax, but form part of what is more properly thought of as a comparative semantics. Semantics, in its broadest sense, is concerned with how linguistic structures are associated with their truth-conditions. A comparative semantics, therefore, is concerned with whether this association can vary from language to language, and if so, what is the cause of this variation. Taking comparative semantics in this way places certain inherent limitations on the search for the sources of variability. This is because the semantic notion of truth is universal, and does not vary from language to language: Sentences either do or do not accurately characterize what they purport to describe. ! The source of semantic variability, therefore, must be somehow located in the way a language is structured.

free from any of the overtones that often constrain professional fisheries meetings. The present volume is the result. This volume aims to be useful as an appraisal of the state of the art by a mixed collection of insiders and outsiders. Most interestingly, I think, it aims (especially in the four group reports) to identify some of the major areas of unresolved controversy and some of the major questions yet unanswered. I see the book as essentially a tentative statement - often by several dissonant voices - about directions in which we may be heading; the book is emphatically not a canonical utterance on how to do things. It is intended to stimulate, not to codify. Following the usual Dahlem Workshop format, the discussions were organized under four themes. Although crisp demarcation is not possible, the first two themes broadly deal with biological aspects of the dynamics of single populations and the dynamics of systems with many species. The later two themes take up questions of management under uncertainty and multispecies management. In all this, the word "fish" is interpreted broadly to include such taxonomically varied beasts as whales, shrimp, crabs, shellfish, and squid, along with fish in a strictly zoological sense.
