This book contains the first documentation of combining house, tree, and person into a single drawing. It helps enrich clinician's test batteries and aids psychologists and physicians in understanding the emotions and self-awareness of their clients. It is richly illustrated and teaches the important skill of using visual metaphors in clinical settings to understand and assist clients. The author covers all aspects of drawing interpretation, including size, placement, stroke or line characteristics, and the possible individual characteristics of each element within the house, tree, and person drawings.

First published in 1972. Routledge is an imprint of Taylor & Francis, an informa company.

House-Tree-Person is a projective personality test, wherein a person responds to a given stimuli, and the responses give clues about the person's hidden emotions or internal conflicts. The individual taking the test is asked to draw primary objects like a house, tree, and a person; that's why the name. These drawings render a measure of self perceptions and attitudes inherent in a personality. The HTP test is adhered to, along with other techniques, in cases where there is likelihood of brain damage, other neurological disorders, or to evaluate brain damage in patients of schizophrenia. It can be taken in any language by anyone who is 3 years old or above. The test consumes around 150 minutes. The person taking the test is first asked to draw, and then is later questioned based on his/her illustration. Usually, the first phase of drawing is colored using crayons, and then pencil is used for the next phase. The instructions given to the test-taker are quite short and simple. "Draw me as good a house as you can", states it well. Once the picture of a house is completed, the test-taker is asked to draw a tree, and later a person. If we are told to draw some object, we might either shy away (for not being good at it) or we might enjoy the process itself (regardless of our artistic abilities). Whichever way, drawing gives us a sense of revisiting our childhood memories full of such fun activities. Similar to writing, the act of drawing forms a powerful medium for us to let our emotions out. As we know, and some of us might even have experienced, that forms of fine art, including drawing, are seen to be stress-releasing activities. Off the mind and onto the paper. This is the knack behind a psychological personality test like the House-Tree-Person test. It is like reading our minds from what we have scribbled or sketched on a sheet of paper. This test is a technique developed by John N. Buck, an early clinical psychologist in 1948, which was later updated in 1969. This, and such other contributions from him are remarkable.

Multiphase systems dominate nearly every area of science and technology, and the method of volume averaging provides a rigorous foundation for the analysis of these systems. The development is based on classical continuum physics, and it provides both the spatially smoothed equations and a method of predicting the effective transport coefficients that appear in those equations. The text is based on a ten-week graduate course that has been taught for more than 20 years at the University of California at Davis and at other universities around the world. Problems dealing with both the theoretical foundations and the applications are included with each chapter, and detailed solutions for all problems are available from the author. The course has attracted participants from chemical engineering, mechanical engineering, civil engineering, hydrologic science, mathematics, chemistry and physics.

Volume 2 (1948-1968) first appeared in 1970. It covers the history of the World Council of Churches from its first assembly at Amsterdam to its fourth assembly at Uppsala, Sweden; analyzes the development of regional ecumenical organizations; and recounts the impact of the Second Vatican Council on the ecumenical witness of the Roman Catholic Church.
