Perspectives in Global Helioseismology, and the Road Ahead

We review the impact of global helioseismology on key questions concerning the internal structure and dynamics of the Sun, and consider the exciting challenges the field faces as it enters a fourth decade of science exploitation. We do so with an eye on the past, looking at the perspectives global helioseismology offered in its earlier phases, in particular the mid-to-late 1970s and the 1980s. We look at how modern, higher-quality, longer datasets coupled with new developments in analysis, have altered, refined, and changed some of those perspectives, and opened others that were not previously available for study. We finish by discussing outstanding challenges and questions for the field.Comment: Invited review; to appear in Solar Physics (24 pages, 6 figures

Criticism and Conversational Texts: Rhetorical Bases of Role, Audience, and Style in the Buber-Rogers Dialogue

This essay describes conversation as an ensemble accomplishment that can be illuminated by critics working with specific texts within a rhetorical framework. We first establish dialogue as the key concept for any criticism of conversation, specifying the rhetorical dimensions of interpersonal dialogue. Second, we show how template thinking is particularly dangerous for conversational critics and suggest a research (anti)method, based on a coauthorship, that provides a thoroughgoing dialogical access to texts. Finally, we exemplify dialogic criticism of a conversational text by analyzing the famous 1957 dialogue of philosopher Martin Buber and psychologist Carl Rogers
