We extend Følner’s amenability criterion to the realm of general topological groups. Building on this, we show that a topological group G is amenable if and only if its left-translation action can be approximated in a uniform manner by amenable actions on the set G. As applications we obtain a topological version of Whyte’s geometric solution to the von Neumann problem and give an affirmative answer to a question posed by Rosendal.

Chapter 1 describes practical theology as a communicative operational science and stresses how important it is that a hermeneutical and narrative approach compliments it. It is shown that pastoral work must be launched from the church community. The premise is that the Enlightenment paradigm causes a reductionistic, individualistic and denominational approach to pastoral work. A holistic, comprehensive and ecologically orientated approach is proposed. Chapter 2 discusses the need for an ecosystemic approach as a metaparadigrn for practical theology in terms of the move away from the Newtonian view of science and the post-modem critiques of a technocratic society. This is supported by developments in systemic family therapy, constructionism and community psychology. Chapter 3 describes an interrelated ecclesiology as a base theory for practical theology and pastoral work with reference to the church's interrelation with society and the need to include an anthropology as part of an ecclesiology. This interrelationship implies that the serving (diakonia) and caring (koinonia) functions of the church should converge, forming a diaconal pastorate. In chapter 4 the secularised modem world-vie\v and the traditional African world-view, both functioning in South Africa, are employed to shed light upon the importance of the concept community for the church's pastoral work. The term community is broadened to include the idea of networking, emphasisingg that community is more than geographical proximity. Chapter 5 is a quantitative investigation. by means of a questionnaire, of the views (ecosystemic/non-ecosystemic) of pastoral workers regarding the church and of pastoral work. Chapter 6 discusses the implications of a community pastoral work approach. Pastoral work has a serving-caring role, but should also function prophetically, to conscientise. sensitise and empower people. The church as a healing community must become the springboard from which pastoral actions can face the challenge of AIDS (chapter 7). This will require the church to shift its paradigm from the reductionist, individualist approach, presently prevalent in society and church pastoral actions, to an all-encompassing. holistic one. / Practical Theology / Th.D.
