This volume comprehensively compares and contrasts alternative models of and treatment approaches to clinical depression. Each contributor, a recognized expert in their modality, analyzes the same case and provides: an overview of the treatment model empirical evidence for both the model and treatment derived from it treatment strategies and interventions, including termination issues, relapse prevention, and recommendations for follow-up care Among the 12 approaches presented are Object Relations, Cognitive Therapies, Schema-Focused, Couple and Family, Integrative Psychotherapy as well as Psychopharmacology. A significant contribution to this volume is the chapter on cultural considerations for understanding, assessing and treating depression.
Phobias A Handbook of Theory, Research and Treatment Edited by Graham C. L. Davey University of Sussex, UK<br> * A complete summary of current knowledge about phobias, for the academic and clinician<br> * First comprehensive handbook on the topic for 10 years<br> * The latest research and findings presented in a single source<br> * Contributions from eminent international clinicians and researchers<br> Psychological treatments available for specific phobias have been refined considerably in recent years. This extensive handbook acknowledges these treatments and includes the description and nature of prevalent phobias, details of symptoms, prevalence rates, individual case histories, and a brief review of our knowledge of the aetiology of phobias. Key knowledge about phobias is brought together in this one critical and accessible handbook, which saves the busy clinician time and provides an authoritative guide to the literature. It is systematically compiled to act as a working tool providing an integrated, contemporary account of prevalent specific phobias, their treatment and theoretical issues concerning aetiology. The Handbook also reflects the important role of cognitive factors in psychopathology which generate and maintain phobic disorders, a process that is now recognized as important in their understanding and treatment. "The joy of Davey's book is that it skillfully blends the historical conditioning theory perspective with current cognitive-behaviour theories . the result is a complete summary of current knowledge about phobias, for clinicians and researchers . an invaluable handbook and an essential summary of the status of theory, research and treatment in phobias. It is highly recommended to researchers and to both novice and experienced clinicians." Roz Shafran, Behaviour Research and Therapy
Polyelectrolytes are used in water treatment systems for a variety of applications including coagulation, flocculation, ballasted sedimentation, filtration, dissolved air flotation, and sludge conditioning. There are multiple advantages to using polyelectrolytes including more efficient removal of particles, organics, and color; reduced sludge formation; sludge conditioning; and reduced reliance on metal salts. This project was developed to determine the degree to which organic polyelectrolytes react with other chemicals used in water treatment applications. The objectives of this project were to: evaluate current patterns of chemical use for drinking water production; conduct bench-scale testing to evaluate polyelectrolyte interactions and the impacts of these interactions on process performance, water quality, and operations; assess the degree to which exposure to ultraviolet light impacts polyelectrolyte reactions with oxidants; and assess the effect of precoating filter media with various polyelectrolytes on filtration efficiency and filter backwashing effectiveness. The research approach included an Internet survey, development of direct and indirect characterization methods to assess polyelectrolyte activity, bench-scale testing of polyelectrolyte interactions with other chemicals, and pilot-scale testing. Screening tools included organic carbon oxidation, absorption spectra, and reactions with oxidants. Performance measures for polymer effectiveness included tests of particle size, filtration rate, and residual turbidity. Disinfection by-product formation potentials were also used to compare the relative degree of oxidation that occurs for individual polyelectrolytes. Pilot-scale tests were conducted to evaluate the effects of precoating filter media with polyelectrolytes on filter run times and filter ripening. A fluorescently labeled version of one of the polyelectrolytes was used to determine the fate of the polyelectrolytes through water treatment systems.
