Power deposition in ferromagnetic implants of cylindrical and spherical shape from an externally applied uniform time harmonic radio-frequency magnetic field has been investigated by means of quasi-static analysis. Inductive heating efficiency is related to the relative permeability and temperature dependence of permeability can be exploited to limit the maximum temperature rise to the desired value by proper choice of Curie point of ferromagnetic material. It is found that theoretically calculated power absorption versus orientation of the cylindrical implant with the direction of magnetic field is in good agreement with the experimental results. The parametric studies are based on a two-dimensional finite difference model for calculating temperature distribution in perfused tissues due to induction heating of an array of implants. An approximate analytical model was developed for a large regular array of implants in perfused tissues. The results of the analytical model are compared with those of the numerical model.

The underlying assumptions of Western counselling and psychotherapy are based on Western European values such as individualism and autonomy. How applicable then are the goals and practices of Western counselling and psychotherapy when applied to non-Western cultures? This research study interviews eight Western-trained Chinese counsellors/psychotherapists who have experience with counselling both Western European clients and Chinese clients. It was found that the establishment of rapport using traditional Western counselling theories has varying amounts of success depending on (a.) the familiarity of the client to Western values, (b.) the familiarity of the counsellor/psychotherapist with Chinese values, (c.) the awareness to not apply knowledge of a client's culture in a stereotypical way, and (d.) the willingness of the counsellor/psychotherapist to be open, flexible, and patient in negotiating a process that fits comfortably with BOTH the particular counsellor/psychotherapist's cultural bias and the particular client's cultural bias.

The purpose of this study was to understand the meaning of change through therapeutic enactment in psychodrama. Existential and hermeneutic phenomenology conducted from the perspective of a dialectic between storied narrative and thematic analysis was used to investigate the essential meaning of the experience. Eight co-researchers who had experienced significant change through therapeutic enactment in psychodrama were interviewed in depth. Transcripts from these interviews were transposed into narrative form in order to straighten the story of change through enactment in a before, during, and after sequence. These eight individual narratives were validated by the co-researchers. An independent reviewer checked each narrative against the original transcript, video tapes of the enactments, and comments of each co-researcher for trustworthiness. Each validated narrative provided a rich description of the lived experience of change through therapeutic enactment. In addition, fifty-nine (59) essential themes were formulated from the individual narratives: Fourteen (14) in the planning stage, twenty-four (24) in the enactive stage, and twenty-one (21) in the reflective, or integrative stage, of the enactment process. These themes were then woven into a common story representing the pattern and meaning of change through therapeutic enactment for this group of co-researchers. Finally, notations made during the transposing of the transcripts into personal narratives, formulation of the essential themes, and construction of the common story were used to develop a theoretical story of change through therapeutic enactment, as a final level of hermeneutic interpretation. This theoretical story was then presented in summary form as a thematic sequence of multi-modal change processes representing a model of change through therapeutic enactment. The results of this study suggested numerous theoretical and technical implications. Foremost among theoretical implications was the suggestion that Tomkins (1992) script theory of affect may best illuminate the effects and processes of psychodrama and enactment. This study also had implications for interactional theories of development, contemporary psychoanalytic theories of interpersonal functioning, theories of moral development, theories of dream functioning, and ethological theories of myth and ritual. The results of this study also suggested a number of additional qualitative and comparative outcome studies for future research.
