Lyapunov vs. Geometrical Stability Analysis of the Kepler and the Restricted Three Body Problem

In this letter we show that although the application of standard Lyapunov analysis predicts that completely integrable Kepler motion is unstable, the geometrical analysis of Horwitz et al [1] predicts the observed stability. This seems to us to provide evidence for both the incompleteness of the standard Lyapunov analysis and the strength of the geometrical analysis. Moreover, we apply this approach to the three body problem in which the third body is restricted to move on a circle of large radius which induces an adiabatic time dependent potential on the second body. This causes the second body to move in a very interesting and intricate but periodic trajectory; however, the standard Lyapunov analysis, as well as methods based on the parametric variation of curvature associated with the Jacobi metric, incorrectly predict chaotic behavior. The geometric approach predicts the correct stable motion in this case as well.Comment: 9 pages, 14 figure

Pragmatic Identity Analysis as a Qualitative Interview Technique

In this article, we examine a qualitative interview and analytical technique for exploring the influences of identities on an individual's experiences. The technique, pragmatic identity analysis (PIA), relies upon a collaborative, reflective, contextually oriented, and relational approach to interviewing. For the purposes of this technique, "identity" is understood as a unique collection of dynamic identities that manifest in diverse contexts. Through narrative dialogue the interview pair jointly reflects upon the identities of the interviewee. They then analyze how identities play a role in the individual's experiences and the formation of values, dispositions towards enacting values, and the sense of wellbeing in different contexts. To examine the efficacy of the technique we present a case study of a first year teacher's growing awareness of her identities and the influence of her identities on her transition to a teaching role.In diesem Beitrag beschäftigen wir uns mit einem Erhebungs- und Auswertungsverfahren, das auf die Untersuchung der Bedeutung von Identität(en) für individuelle Erfahrungen zielt. Diese Methodik, die pragmatische Identitätsanalyse, basiert auf einem kollaborativen, reflexiven, kontextorientierten und relationalen Verständnis von Interviewen. Dabei fassen wir "Identität" als einzigartige Sammlung dynamischer Identitäten, die sich in unterschiedlichen Kontexten manifestieren. Im Rahmen eines narrativen Dialogs reflektiert ein Interviewer/innentandem gemeinsam auf die Identitäten des/der Interviewten. Danach analysieren sie, welche Bedeutung diesen Identitäten für die Erfahrungen, Wertebildung und für das Wohlbefinden des/der Interviewten in unterschiedlichen Settings zukommt. Um die Wirksamkeit des Ansatzes zu veranschaulichen, nutzen wir eine Fallstudie mit einer Junglehrerin zu deren Gewahrwerden ihrer verschiedenen Identitäten im Übergang zur Übernahme der Rolle als Lehrerin

Complexity, Tunneling and Geometrical Symmetry

It is demonstrated in the context of the simple one-dimensional example of a barrier in an infinite well, that highly complex behavior of the time evolution of a wave function is associated with the almost degeneracy of levels in the process of tunneling. Degenerate conditions are obtained by shifting the position of the barrier. The complexity strength depends on the number of almost degenerate levels which depend on geometrical symmetry. The presence of complex behavior is studied to establish correlation with spectral degeneracy.Comment: 9 revtex pages, 6 Postscript figures (uuencoded
