The group therapy process and its effectiveness with chronic schizophrenic patients as a function of the role of the leader.

Thesis (Ph.D.)--Boston UniversityA survey of the literature shows that group psychotherapy with the psychoses, since its inception thirty-five years ago, has assumed a position of major importance as a method of treatment. Despite the widespread use of group therapy, research has not kept pace with the clinical use of this technique. The need for experimentation in this area is recognized. There is general agreement on many fundamental issues that require empirical investigation. In accordance with this consensus regarding the need for basic research, it seemed possible to investigate the following three problems: (l) the effectiveness of group psychotherapy; (2) the relative effectiveness of two different therapeutic approaches; and (3) the influence of the role of the leader upon the group process. The focus in this study of group therapy was on the development of interaction as it is related to the style of leadership

Coulomb force effects in low-energy α\alpha-deuteron scattering

The $\alpha$-proton Coulomb interaction is included in the description of $\alpha$-deuteron scattering using the screening and renormalization approach in the framework of momentum-space three-particle equations. The technical reliability of the method is demonstrated. Large Coulomb-force effects are found.Comment: To be published in Phys. Rev.

Scattering of Two Spinless Particles in 3D Formulation with Coulomb Admixtures

Scattering of two spinless charge particles for simple forces including coulomb admixtures is calculated without partial wave decomposition. The coulomb interaction being taken is of the type of screened coulomb potential. For the forces range are not infinite, the standard scattering theory is applied. The differential and total cross section is calculated and coulomb effects are shown.Comment: 4 pages, 2 figure

New calculation schemes for proton-deuteron scattering including the Coulomb interaction

The Coulomb interaction between the protons is included in the description of proton-deuteron scattering using the screening and renormalization approach in the framework of momentum-space integral equations. Two new calculational schemes are presented that confirm the reliability of the perturbative approach for treating the screened Coulomb interaction in high partial waves, used by us in earlier works.Comment: To be published in Phys.
