Leucinosis--a case of congenital metabolic disease in a child

Trasditional Chinese medicine is based on inductive-synthetic reasoning with regard to all life processes, in contrast to the causal-analytic orientation in our Western medicine. This philosophical approach is based on a system of comparisons (equivalents), referred to as Yin and Yang. Vital functions are seen as "energizing" processes, whereby the acupuncture points and the system of meridians are seen as a means of regulation for this "energy". A disturbed balance in this energy results in illness. The therapy according to the acupuncture method is to acheive a balance in the disturbed flow of energy by means of acupuncture points. By utilizing biophysical methods of measurement, it is possible to prove that a change in this energy takes place. The complex active principle which results in the effectiveness of acupuncture includes neurophysiological, biochemical and biophysical functional processes.

A balance theory of wisdom.

The author presents a balance theory of wisdom. First, some alternative approaches to wisdom are reviewed, including philosophical, implicit theoretical, and explicit theoretical ones. Second, the concept of tacit knowledge and its role in wisdom are discussed. Third, a balance theory of wisdom is presented, according to which wisdom is defined as the application of tacit knowledge as mediated by values toward the achievement of a common good through a balance among multiple (a) intrapersonal, (b) interpersonal, and (c) extrapersonal interests in order to achieve a balance among (a) adaptation to existing environments, (b) shaping of existing environments, and (c) selection of new environments. This theory is compared to some other theories, and wisdom as a construct is compared to some other constructs. Measurement issues are also discussed. It is concluded that it might be worthwhile for American society to emphasize development of wisdom in schooling more than it has in the past.

Balance theory, unit relations, and attribution: The underlying integrity of Heiderian theory.

Fritz Heider's theory of social perception is reviewed, and the close connection between attribution, balance, and unit relationship are examined, primarily through Heider's own writings. Attribution and balance have historically been considered separate theories, but the authors show how these two ideas, in conjunction with the idea of unit formation, create a broad-ranging and integrated theory of social perception. Attributions were seen by Heider as a particular kind of unit relationship, and people make attributions that preserve an affectively consistent view of others. The authors then show how this integrated understanding of Heider's ideas generates new predictions and informs a wide range of clinical, personality, and social psychological phenomena, as a reminder of the modern power of Heider's theory.

Review of Middle-class waifs. The psychodynamic treatment of affectively disturbed children.

Reviews the book, Middle-class waifs. The psychodynamic treatment of affectively disturbed children by Elaine V. Siegel (see record 1991-98014-000). Most of this book is devoted to case histories of children and their parents who have relatively severe emotional problems yet can be sufficiently responsive to psychotherapy so that positive changes occur. Particularly impressive are the ways in which the author, in her therapeutic role, overcomes the resistances presented by both children and parents. She is clearly an excellent therapist, who would probably be effective regardless of orientation, and her manner of working with people has applicability for all psychotherapists. Her appreciation of the necessary balance in understanding the needs of children and their parents is an exemplary model of what it really means to respect the personhood of patients. One of the intriguing possibilities in this book is the case that is made for the broad applicability of psychoanalytic theory and treatment. During a time in which psychodynamic work is being criticized as taking too long, costing too much, and producing too little, the author offers quite a convincing demonstration of its value. The negative consequences of increased disparagement of this approach are also made apparent, so that a definite step is taken to restore the worth of treatment options. Any limitations of this book are minor, relative to the excellent portrayal of the process of psychotherapy with difficult patients that too often frighten or overwhelm people who could help them if the helpers would let themselves discover how. This work by a master clinician definitely points the way. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
