Theoretical Systems Ecology

Theoretical Systems Ecology: Advances and Case Studies aims to relate systems ecology theory to theoretical systems ecologists and other theoreticians in systems science. The main language of systems theory is mathematics. This book somewhat simplifies concepts, advances, and developments of the field to non-mathematicians who lack background in some aspects of systems ecology. It presents examples after every chapter that shows the application of theory to the development and analysis of models. This book generally focuses on three problems. The first problem is the selection of components found in the system model. The definition of the relationships and interactions between the system variables is another concern of this book. It also looks into the model analysis. These problems are thoroughly discussed in each section of the book. The theory of modeling, formalisms, classes, and properties of models are covered in the first two sections of this book. A whole section in this book is dedicated to Systems Identification and deals mostly with the problem of extracting information from data. Other sections cover model analysis with focus on trends in some aspects, such as stability and control theory.

Here is a book that challenges the very basis of the way psychologists have studied child development. According to Urie Bronfenbrenner, one of the world's foremost developmental psychologists, laboratory studies of the child's behavior sacrifice too much in order to gain experimental control and analytic rigor. Laboratory observations, he argues, too often lead to "the science of the strange behavior of children in strange situations with strange adults for the briefest possible periods of time." To understand the way children actually develop, Bronfenbrenner believes that it will be necessary to observe their behavior in natural settings, while they are interacting with familiar adults over prolonged periods of time. This book offers an important blueprint for constructing such a new and ecologically valid psychology of development. The blueprint includes a complete conceptual framework for analysing the layers of the environment that have a formative influence on the child. This framework is applied to a variety of settings in which children commonly develop, ranging from the pediatric ward to daycare, school, and various family configurations. The result is a rich set of hypotheses about the developmental consequences of various types of environments. Where current research bears on these hypotheses, Bronfenbrenner marshals the data to show how an ecological theory can be tested. Where no relevant data exist, he suggests new and interesting ecological experiments that might be undertaken to resolve current unknowns. Bronfenbrenner's groundbreaking program for reform in developmental psychology is certain to be controversial. His argument flies in the face of standard psychological procedures and challenges psychology to become more relevant to the ways in which children actually develop. It is a challenge psychology can ill-afford to ignore.

Possibly the first textbook to present a practically applicable ecosystems theory, Introduction to Systems Ecology helps readers understand how ecosystems work and how they react to disturbances. It demonstrates—with many examples and illustrations—how to apply the theory to explain observations and to make quantitative calculations and predictions. In this book, Sven Erik Jørgensen takes a first step toward integrating thermodynamics, biochemistry, hierarchical organization, and network theory into a holistic theory of systems ecology. The first part of the book covers the laws of thermodynamics and the basic biochemistry of living organisms, as well as the constraints they impose on ecosystems. To grow and develop, however, ecosystems have to evade these thermodynamic and biochemical constraints, so the second part of the book discusses the seven basic properties that enable ecosystems to grow, develop, and survive: They are open systems, far from thermodynamic equilibrium. They are organized hierarchically. They have a high diversity. They have high buffer capacities toward changes. Their components are organized in cooperative networks, which allows for sophisticated feedback, regulation mechanisms, and higher efficiencies. They contain an enormous amount of information embodied in genomes. They have emerging system properties. This timely textbook also looks at how systems ecology is applied in integrated environmental management, particularly in ecological modeling and engineering and in the assessment of ecosystem health using ecological indicators. Acknowledging that there is still much room for improvement, it will inspire ecologists to develop a stronger and more widely applicable ecosystem theory.

The book presents a consistent and complete ecosystem theory based on thermodynamic concepts. The first chapters are devoted to an interpretation of the first and second law of thermodynamics in ecosystem context. Then Prigogine's use of far from equilibrium thermodynamic is used on ecosystems to explain their reactions to perturbations. The introduction of the concept exergy makes it possible to give a more profound and comprehensive explanation of the ecosystem's reactions and growth-patterns. A tentative fourth law of thermodynamic is formulated and applied to facilitate these explanations. The trophic chain, the global energy and radiation balance and pattern and the reactions of ecological networks are all explained by the use of exergy. Finally, it is discussed how the presented theory can be applied more widely to explain ecological observations and rules, to assess ecosystem health and to develop ecological models.

Praise for the first edition "Finally, a social work practice text that makes a difference! This is the book that you have wished for but could never find. Although similar to texts that cover a range of practice theories and approaches to clinical practice, this book clearly has a social work frame of reference and a social work identity." --Gayla Rogers, Dean of the Faculty of Social Work, University of Calgary The major focus of this second edition is the same; to provide an overview of theories, models, and therapies for direct social work practice, including systems theory, attachment theory, cognitive-behavioral theory, narrative therapy, solution-focused therapy, the crisis intervention model, and many more. However, this popular textbook goes beyond a mere survey of such theories. It also provides a framework for integrating the use of each theory with central social work principles and values, as well as with the artistic elements of practice. This second edition has been fully updated and revised to include: A new chapter on Relational Theory, and newly-rewritten chapters by new authors on Cognitive-Behavioral Theory, Existential Theory, and Wraparound Services New critique of the Empirically Supported Treatment (EST) movement Updated information on the movement toward eclecticism in counseling and psychotherapy A refined conceptualization of the editors' generalist-eclectic approach

Pardeck demonstrates that the ecological approach to social work practice stresses effective intervention, and that effective intervention occurs through not only working with individuals, but also with the familial, social, and cultural factors that impact their social functioning. The power of the ecological approach, through focusing on multiple factors for assessment and intervention, is that it integrates empirically based theories from various fields including social work, psychology, sociology, and anthropology. Pardeck provides an orientation to the role of social work practitioners within the human services. He differentiates the unique contributions of social work and explains them in terms of the needs and goals of an ecological approach to practice. An ecological approach to practice stresses that effective social work intervention occurs through not only working with individuals, but also with the familial, social, and cultural factors that impact their social functioning. The power of the ecological approach, through focusing on multiple factors for assessment and intervention, is that it integrates empirically based theories from various fields including social work, psychology, and anthropology. The book represents an effort to define the goals, commitments, and approaches that have emerged out of the history of social work and to relate them to similar concepts and values that are central to an ecological approach to practice. Three pervasive and unifying themes run through the book. One is the constant commitment to goals of facilitating human development. Pardeck suggests this is a central ethic that defines and distinguishes an ecological approach to social work practice. The second theme is an affirmation of the basic utility of a systems approach in conceptualizing and intervening in human needs, concerns, and problems. The ecological perspective views human beings as social organisms engaged in patterns of relationships that nurture or inhibit this basic humanity. The third theme is an interactionist view of the importance of person-environment fit as a central dynamic in human functioning. The traditional intra-psychic aspects of human behavior have tended to obscure the immense importance of both nurturing and potentially damaging forces at work in the social environment. This volume will be of considerable interest to social work educators and practitioners as well as their research libraries.

Presents an overview of ecological modeling as it relates to current ecological theory. KEY TOPICS: A Primer of Ecological Theory maintains its scientific objectivity while covering the full extent of current ecological modeling theory. The book introduces the use of computer technology to ecological modeling through MATLAB. This allows all work to be verified and the skills transferred to other disciplines. MARKET: A valuable resource book for ecologists, resource managers, and economists.

Theoretical Ecology: concepts and applications continues the authoritative and established sequence of theoretical ecology books initiated by Robert M. May which helped pave the way for ecology to become a more robust theoretical science, encouraging the modern biologist to better understand the mathematics behind their theories. This latest instalment builds on the legacy of its predecessors with a completely new set of contributions. Rather than placing emphasis on the historical ideas in theoretical ecology, the Editors have encouraged each contribution to: synthesize historical theoretical ideas within modern frameworks that have emerged in the last 10-20 years (e.g. bridging population interactions to whole food webs); describe novel theory that has emerged in the last 20 years from historical empirical areas (e.g. macro-ecology); and finally to cover the rapidly expanding area of theoretical ecological applications (e.g. disease theory and global change theory). The result is a forward-looking synthesis that will help guide the field through a further decade of discovery and development. It is written for upper level undergraduate students, graduate students, and researchers seeking synthesis and the state of the art in growing areas of interest in theoretical ecology, genetics, evolutionary ecology, and mathematical biology.
