    Notes: Abstract In this paper we continue to extend our previous investigation of continued fraction (CF) solutions for the stationary probability of discrete one-variable master equations which generally do not satisfy detailed balance. We derive explicit expressions, directly in terms of the elementary transition rates, for the continued fraction recursion coefficients. Further, we derive several approximate CF-solutions, i.e., we deduce non-systematic and systematic truncation error estimates. The method is applied to two master equations with two-particle jumps for which we derive the exact probability solution and make a comparison with approximate solutions. The investigation is also extended to the case of master equations with multiple birth and death transitions of maximal orderR.

    Notes: Abstract Two methods for finding stationary solutions of discrete master equation in general cases without detailed balance are set up and compared for the case of the Laser equation. The first method starts from a reduced master equation obtained for appropriate forms of the Liouvillean, the second from a variational principle for the stationary solution of the full master equation. In the Laser case, both methods lead to forms of the stationary solution essentially equivalent to the result of Dohm.

    Notes: Abstract We present the continued fraction solution for the stationary probability of discrete master equations of one-variable processes. After we elucidate the method for simple birth and death processes we focus the study on processes which introduce at least two-particle jumps. Consequently, these processes do in general not obey a detailed balance condition. The outlined method applies as well to solutions of eigenmodes of the stochastic operator. Further we derive explicit continued fraction solutions for the Laplace transform of conditional probabilities. All the various continued fraction coefficients are given directly in terms of the transition rates and they obey recursion relations. The method is illustrated for the stationary solution of a simple nonlinear chemical reaction scheme originated by Nicolis.

    Notes: Abstract We introduce “transition factors” and derive equations for them which are equivalent to the originalN-dimensional discrete master equation. After transition to continuous variables we obtain nonlocal partial differential equations for these transition factors which are slowly varying variables. Finally we consider a chemical reaction system. Using this method the corresponding master equation is exactly solvable in a very simple manner.

    Notes: Abstract A systematic algorithm for finding solutions of Fokker Planck systems with time-dependent drift and fluctuation coefficients is developed. The solutions lag behind the adiabatic quasistationary distribution. This delay effect vanishes for slowly varying control parameters. In a first example the evolution of the phase transition from a monostable to a bistable system is treated. There is a fluctuation enhancement and the delay of the probability distribution leads to a transient central peak. In a second example a linear model with time-dependently shifted drift is considered. The introduced approximation scheme reproduces the exact solution already in first order.

    Description / Table of Contents: Summary Deficits in current approaches of psychosomatic and psychiatric education for general practitioners are reviewed. A skill-based training was developed in line with the four step counceling approach of the „PLISSIT” approach: The GP helps in first step („permission”) the patient to accept his problem and assesses informations about causing and maintaining factors of his symptomatology. In the second step he should provide information about the disorder and reverse misunderstanding and passivity (Limited Information). The GP’s should develop preliminary strategies for change in the third step („coping strategies”, „symptom management”; „special suggestions”) and preparate the intensive phase of therapy as the last step. First results of the evaluation of the training program are presented demonstrate the effectiveness and acceptance of the education programm.
    Notes: Zusammenfassung Ausgehend von einer Analyse der Schwächen aktueller Ansätze der psychosomatischen Grundversorgung wird einerseits ein Ansatz vorgestellt, der störungsspezifisch im Rahmen eines Mehrebenenmodells pharmakologische und verbale Intervention aufeinander bezieht. Andererseits werden im Sinne eines zeitökonomisch abgestuften Vorgehens verschiedene Phasen durch das zugrundegelegte PLISSIT-Modell differenziert: In der Permission-Phase geht es um die Akzeptanzvermittlung und Problemanalyse hinsichtlich der vom Patienten geschilderten Beschwerden, in der Phase der „limited information” um die dialogische Erarbeitung eines Störungsmodells und den Aufbau einer aktiven Änderungsmotivation, in der Phase der „special suggestions” erfolgt eine konkrete Anleitung zur Selbstbeobachtung und -protokollierung des Problemverhaltens sowie die Vermittlung von Strategien zum Symptommanagement; in der letzten Phase der „intensive therapy” geht es um die Indikationsstellung und den Motivationsaufbau zur fachärztlichen bzw. fachpsychotherapeutischen Weiterbehandlung. Empirische Ergebnisse zur Evaluation des Weiterbildungskonzeptes an über 200 Teilnehmern werden referiert.
