Participatory development in South Africa: a development management perspective, follows a holistic, multidisciplinary approach in assessing development management principles and strategies in South Africa. The authors represent a broad teaching, research and management background, which allows them to functionally integrate some of the most important challenges in development management and related practice and policy interventions in this title. The work therefore captures the fundamental basis upon which most development projects and practices are based, namely cooperation, collaboration and public participation.

This book approaches economic problems from a systems thinking and feedback perspective. By introducing system dynamics methods (including qualitative and quantitative techniques) and computer simulation models, the respective contributions apply feedback analysis and dynamic simulation modeling to important local, national, and global economics issues and concerns. Topics covered include: an introduction to macro modeling using a system dynamics framework; a system dynamics translation of the Phillips machine; a re-examination of classical economic theories from a feedback perspective; analyses of important social, ecological, and resource issues; the development of a biophysical economics module for global modelling; contributions to monetary and financial economics; analyses of macroeconomic growth, income distribution and alternative theories of well-being; and a re-examination of scenario macro modeling. The contributions also examine the philosophical differences between the economics and system dynamics communities in an effort to bridge existing gaps and compare methods. Many models and other supporting information are provided as online supplementary files. Consequently, the book appeals to students and scholars in economics, as well as to practitioners and policy analysts interested in using systems thinking and system dynamics modeling to understand and improve economic systems around the world. "Clearly, there is much space for more collaboration between the advocates of post-Keynesian economics and system dynamics! More generally, I would like to recommend this book to all scholars and practitioners interested in exploring the interface and synergies between economics, system dynamics, and feedback thinking."

Several recent studies have found that anxiety is increasing among college students. In today's competitive college environment, students frequently find themselves overwhelmed with worry and anxiety as they struggle to make the grade academically, fit in socially, "discover who they are," and ponder their futures. This book helps students (and their parents and counselors) deal effectively with predictable anxieties associated with college. The authors offer suggestions and techniques, based on extensive research on the treatment of anxiety, to help students cope more effectively with the common sources of anxiety. In addition, the book describes the most common and debilitating disorders of anxiety (such as panic attacks, phobias, and obsessive-compulsive disorder) that affect more than 10% of Americans and most frequently have their onset during the college years. The initial section of the book begins by describing the scope of the problem of anxiety as it relates to college students. The next section discusses the nature of anxiety reactions, noting the contribution of factors such as biological predisposition and developmental factors. Finally, the third section provides general strategies for managing anxiety such as doing relaxation exercises, challenging negative thoughts and perspectives, and facing fears. Vignettes about college students dealing with anxiety are included throughout.

The series Structure and Bonding publishes critical reviews on topics of research concerned with chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant.

The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience. Thus each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years should be presented using selected examples to illustrate the principles discussed. A description of the physical basis of the experimental techniques that have been used to provide the primary data may also be appropriate, if it has not been covered in detail elsewhere. The coverage need not be exhaustive in data, but should rather be conceptual, concentrating on the new principles being developed that will allow the reader, who is not a specialist in the area covered, to understand the data presented. Discussion of possible future research directions in the area is welcomed. Review articles for the individual volumes are invited by the volume editors.

These Conference Proceedings are intended to summarise the latest developments in diffraction and scattering theory as reported at the IU TAM Symposium on Diffraction and Scattering in Fluid Mechanics and Elasticity held in Manchester, England on 16-20 July 2000. This in formal meeting was organised to discuss mathematical advances, both from the theoretical and more applied points of view. However, its pri mary goal was to bring together groups of researchers working in dis parate application areas, but who nevertheless share common models, phenomenological features arising in such problems, and common math ematical tools. To this end, we were delighted to have four Plenary Speakers, Professors Allan Pierce, Ed Kerschen, Roger Grimshaw and John Willis FRS, who are undisputed leaders in the four thematic ar eas of our meeting (these are respectively acoustics, aeroacoustics, water or other free surface waves, elasticity). These Proceedings should offer an excellent vehicle for continuing the dialogue between these groups of researchers. The participants were invited because of their expertise and recent contributions to this field. Collectively, there were around 90 contrib utors to the Symposium from some 13 countries located all around the world. These included 45 speakers, 35 co-authors and about 10 other delegates. Individuals came from many of the major international cen tres of excellence in the field of scattering theory."

The therapist's ability to listen and respond is the core of establishing an effective therapeutic relationship. This research-supported volume provides thorough models of listening and responding, using an easy to understand approach. Welch demonstrates how learning and responding skills can be learned, practiced, mastered, and embedded in a multicultural world setting where counselors and psychotherapists work with clients daily. Practice exercises are presented to develop listening and responding skills. Counselors, psychotherapists, and students from a variety of disciplines--including counseling, psychology, nursing, and social work--will find that this eclectic work transcends disciplines. Special attention is given to diversity, multicultural concerns, and counseling competencies. This unique text holds particular appeal for those preparing to enter fields including psychotherapy, social work, school guidance programs, health, nursing, and pastoral counseling. It will also interest those at pre-practicum and practicum stages, as well as officials in training centers where students are placed for on-the-job experience. students are placed for on-the-job experience.

Numerous opportunities have come and gone over the past 20 years of democracy in South Africa for the State to engage with Civil Society and bring development closer to its intended beneficiaries. Civil Society, through its advocacy initiatives, has secured for itself a greater voice and choice in development, and every role player therein should continuously endeavour to make a difference by participating actively and meaningfully in development. Authentic, sustainable grassroots transformation and development, however, is not possible without public participation, social learning, self-reliance and empowerment. Development, the State and Civil Society in South Africa addresses the practical reality of the development consultant, government and public sector change agent, politician and policy maker. Departing from a humanist and people-centred perspective, it captures the fundamentals upon which most development theory, policy, programmes/projects and practices are based, namely cooperation, participatory planning and public participation. The book follows a holistic, multidisciplinary approach to assessing development management principles and strategies. Important challenges in development management and related practice and policy interventions are also functionally integrated. Contents include the following: Development theories, management and the democratic developmental State; Promoting people-centred development and good governance; The role of developmental non-governmental organisations; The private sector and social responsibility; The role of trade unions and international development agencies; Micro-level development and public participation; Integrated Development Planning (IDP); Social development research; Chapter review questions test knowledge and understanding of issues discussed, and encourage critical examination from different perspectives. The final chapter provides guidelines for writing scientific documents and using basic social research methodology - essential skills for all researchers and practitioners in development management.

The role of folylpolyglutamates in biosynthetic processes has gained increasing importance with the recognition that these com pounds are not only the forms of folate co-factors that accumulate within cells, but, in addition, are the preferred substrates for folate dependent reactions in eukaryotic cells. More recently attention has turned to the potential importance of the polyglutamyl derivatives of methotrexate that have been detected in normal and malignant cells both in vitro and in vivo. The biochemical trans formation of this important chemotherapeutic agent is of particular significance since polyglutamyl derivatives of methotrexate are not only potent inhibitors of the target enzyme, but have quite different cellular pharmacokinetics than the parent monoglutamate. Hence, nearly three and a half decades after 4-aminoantifolates were first applied clinically in the treatment of human neoplasms, we have begun to appreciate a new dimension in antifolate pharmaco logy which may have profound implications for our understanding of the mechanism of the cytotoxicity and selectivity of this class of agents. With the development of highly sensitive methodology for the rapid detection of folyl and antifolyl polyglutamates, it is now possible to define in depth the intracellular transformation of these agents and their role in determining antifolate action against normal and malignant cells. This information will very likely influence how regimens with methotrexate and related antifolates will be further developed and employed clinically."

The bond valence model, a description of acid-base bonding, is widely used for analysing and modelling the structures and properties of solids and liquids. Unlike other models of inorganic chemical bonding, the bond valence model is simple, intuitive, and predictive, and is accessible to anyone with a pocket calculator and a secondary school command of chemistry and physics. This new edition of 'The Chemical Bond in Inorganic Chemistry: The Bond Valence Model' shows how chemical properties arise naturally from the conflict between the constraints of chemistry and those of three-dimensional space. The book derives the rules of the bond valence model, as well as those of the traditional covalent, ionic and popular VSEPR models, by identifying the chemical bond with the electrostatic flux linking the bonded atoms. Most of the new edition is devoted to showing how to apply these ideas to real materials including crystals, liquids, glasses and surfaces. The work includes detailed examples of applications, and the final chapter explores the relationship between the flux and quantum theories of the bond.
