Traditional societies are characterized by festivals of various kinds and dimensions. Some distinctly manifest aspects of the community rituals or worship, some celebratory; yet others function towards social change. Irrespective of their types, underlying the different forms of community performance is likely to be found the central element of ritual associated with one aspect of community belief or another. Among the Igbo of south-eastern Nigeria, Omerife is a festival associated with the ritual of new yam celebrations. In a sense, the (...) ceremonies of the new yam are thanksgiving activities whereby the gods are propitiated with sacrifices for a bountiful harvest as well as for a peaceful farming year. However, the festival also embodies different community forms of performances such as the Ogene- nkirika. Ogene-nkirika is the first part of the two-tiered festival. This paper examines the aspect of conflict that motivates the process of social change on the theoretical premise of Theatre for Reciprocal Violence (TRV) to foreground conflict as pertinent for change in the performance. Case study approach of qualitative research method was adopted for data collection and analysis. The study reveals that Ogene-nkirika festival performance is capable of engendering social change for the people through conflict as reflected in the analysis. (shrink)

‘‘Theoretical biology’’ is a surprisingly heter- ogeneous field, partly because it encompasses ‘‘doing the- ory’’ across disciplines as diverse as molecular biology, systematics, ecology, and evolutionary biology. Moreover, it is done in a stunning variety of different ways, using anything from formal analytical models to computer sim- ulations, from graphic representations to verbal arguments. In this essay I survey a number of aspects of what it means to do theoretical biology, and how they compare with the allegedly much more restricted (...) sense of theory in the physical sciences. I also tackle a recent trend toward the presentation of all-encompassing theories in the biological sciences, from general theories of ecology to a recent attempt to provide a conceptual framework for the entire set of biological disciplines. Finally, I discuss the roles played by philosophers of science in criticizing and shap- ing biological theorizing. (shrink)
