Antisymmetry and channel coupling contributions to the absorption for p + alpha/d + 3He

To understand recently established empirical p + alpha potentials, RGM calculations followed by inversion are made to study contributions of the d + 3He reaction channels and deuteron distortion effects to the p + alpha potential. An equivalent study of the d + 3He potential is also presented. The contributions of exchange non-locality to the absorption are simulated by including an phenomenological imaginary potential in the RGM. These effects alone strongly influence the shape of the imaginary potentials for both p + alpha and d + 3He. The potentials local-equivalent to the fully antisymmetrised-coupled channels calculations have a significant parity-dependence in both real and imaginary components, which for p + alpha is qualitatively similar to that found empirically. The effects on the potentials of the further inclusion of deuteron distortion are also presented. The inclusion of a spin-orbit term in the RGM, adds additional terms to the phase-equivalent potential, most notably the comparatively large imaginary spin-orbit term found empirically.Comment: 17 pages, Latex, 8 postscript figs, submitted to Nucl.

Determination of Li-6 -- He-4 interaction from multi-energy scattering data

We present the first successful potential model description of Li-6 -- He-4 scattering. The differential cross-sections for three energies and the vector analyzing powers for two energies were fitted by a single potential with energy dependent imaginary components. An essential ingredient is a set of Majorana terms in each component. The potential was determined using a recently developed direct data-to-potential inversion method which is a generalisation of the IP S-matrix-to-potential inversion algorithm. We discuss the problems related to this phenomenological approach, and discuss the relationship of our results to existing and future theories.Comment: 9 pages plain LaTeX, 6 postscript figue

The inter-experiential field: Perceptions and metaperceptions in person-centered and experiential psychotherapy

How can we understand the complex nexus of interpersonal relationships from a phenomenological, experiential standpoint? Drawing on theory and research from R. D. Laing's interpersonal phenomenology, social psychology, and Interpersonal Psychotherapy, this paper examines the disjunctions that may arise in people's perceptions of each other, and the highly destructive consequences that such disjunctions can have. It explores the questions of how people perceive, and misperceive, other people's experiences; how people perceive, and misperceive, others' perceptions of their experiences ('metaperceptions'); and the implications that such an analysis has for the practice of person-centered and experiential psychotherapy and counseling

The fires of change: Kirk, Popper, and the Heraclitean debate

In this paper, I explore a prominent question of Hericlitean scholarship: how is change possible? Karl Popper and G. S. Kirk tackle this same question. Kirk asserts that Heraclitus believed that change is present on a macrocosmic level and that all change is regulated by the cosmic principle logos. Popper, on the other hand, claims Heraclitus believed that change is microcosmic and rejected that all change is regulated by logos. I argue for a combination of aspects from each of their claims and conclude that change is present both microcosmically and macrocosmically and that all change is governed by logos

Building a Community Around the Writing Center

Recruitment and retention are important issues on every campus but especially so on small campuses like that of Casper College. My predecessor, Bob Mittan, believed as I do that the Writing Center should serve as a community as well as a campus resource. His reasons focused on how the community could be involved with the writing center while my reasons focus on how the writing center can be involved with the community. In becoming a community resource, our center serves to demystify academe both for those in the community who feel they are too old or incapable to succeed in college and for young writers in high school who may not have decided to attend college yet. As a result, we are acquiring something of a reputation for helping students and community members with résumé cover letters and creative writing projects as well as scholarship letters and essays.University Writing Cente
