The paper presents a theory of the industrial transformation amongst sectors using endogenous growth theory. Allowing only a slight upward trend in the productivity of the human capital sector, combined with ascending degrees of human capital shares of sectoral output, in say, agriculture, manufacturing and services, output gradually shifts relatively over time from agriculture to manufacturing and to services. Abstracting from international trade theory, sectors intensive in the factor that is becoming relatively more plentiful find their relative outputs expanding. Adding more sectors of greater human capital intensity causes labor time to decrease within each sector, as shown for agriculture, and in general for any number of sectors.
The history, conception, & uses of the term public sphere are explored. A recounting of initial & subsequent political usage draws on statements by Kane, Tonnies, Habermas, Garnham, & Arendt. There is consideration of conflicts between populist & market-driven motivations for control of public information. A survey of the early 20th-century rise of public service broadcasting is followed by details of its weakening. Investigation of causes for the ongoing crisis in public service media links public sphere theory with major factors, including financial instability, questions of legitimacy, & technological evolution. A tracing of changes in the nature of populist space & discourse includes examination of micro-, meso-, & macropublic spheres. Acceptance of the complexities attending public spheres discussion calls for ongoing assessment of volatile issues including pluralism, political geography, distinctions between public & private zones, transience, & the need for a shift in definitions to include cultural phenomena such as talk shows & video games. 34 References.
