We present an elementary method for proving enumeration formulas which are polynomials in certain parameters if others are fixed and factorize into distinct linear factors over Z. Roughly speaking the idea is to prove such formulas by “explaining” their zeros using an appropriate combinatorial extension of the objects under consideration to negative integer parameters. We apply this method to p...

Almost a century has elapsed since the Gestalt psychologists first emphasized the importance of internal organization processes to perception. The work of Gestaltists has had an enormous influence on perceptual psychology; largely through their compelling visual demonstrations which can be found in most textbooks on perception. However, Gestalt concepts such as Pragnanz, isomorphism, wholism, a...

Lead Zirconate Titanate, PZT, layered into a composite with different materials, produces pre-stressed, curved, devices capable of enhanced displacement. This study focuses on Thunder and Lipca which are built using different combinations of constituent materials. Thunder devices consist of layers of aluminum, PZT, and stainless steel bonded with a hot-melt adhesive. Lipca devices consist of ca...

The paper is devoted to the further study of the remarkable classes of orthogonal polynomials recently discovered by Bender and Dunne. We show that these polynomials can be generated by solutions of arbitrary quasi exactly solvable problems of quantum mechanichs both one-dimensional and multi-dimensional. A general and model-independent method for building and studying Bender-Dunne polynomials ...

Four aspects of Gestalt practice that are particularly relevant to HIV-related therapy are explored: the client-therapist relationship, the phenomenonological method, awareness as the goal of therapy, and experiments and role playing. Applying the Gestalt ideals of self-regulation, wholeness, and growth to a person with HIV is vital to counteract the patient's loss of immune function. The Gesta...

In a formerpaper2we pointed out thatthe term 'Gestalt' is being used in at least two essentially different meanings. We suggested limiting the use of the term 'Gestalt' to its original meaning, i.e. 'shape' , 'form' or 'configuration'. Its other meaning is often expressed by 'functional (or organized) whole'; we used3 the expression 'determinational system' [Wirkungssystem] instead. In the form...

Objectives: Loneliness is a common experience of people, regardless of gender, age, socio economic and cultural experience in the course of its life. The aim of this study was to examine the effectiveness of Gestalt group therapy on the loneliness of Alzheimer’s caregivers. Methods: In an experimental study with a pre-post test design and control group, women participants were selected...
