Conventional regression analysis can only produce ＂average＂ and ＂global＂ parameter estimates rather than ＂local＂ parameter estimates which vary over space in some spatial systems. Geographically weighted regression （GWR）, on the other hand, is a simple but useful new technique for the analysis of spatial non-stationarity. Results show that there is a significant difference between OLS and GWR in estimating the parameters of R＆D knowledge production, and that the relationships between level of regional innovation activities and various factors show considerable spatial variability.展开更多

The cultural deficiencies symbolized by such ＂second-hand reading＂ t＇md their expression in three phenomena： first, the audience, eager to become culturally enlightened, find themselves in the passive role of mere receivers of scholars＇ interpretations of the classics, lacking the role of autonomous readers. Second, the media, motivated by commercial aims, opt for an inappropriate cultural strategy and over-reach their proper role. Third, scholars, taking their orientation from the powerful mass media and following the commercial logic that ＂the audience is king,＂ settle for a misplaced role and degenerate from being ＂guides to the best in culture＂ into merely catering to mass taste. To redress such a situation, our strategy should be to coordinate the universities, public libraries, the media and other public resources in a concerted effort to switch from ＂second-hand reading＂ led by the media to self-initiated ＂autonomous reading,＂ so as to rebuild a public intellectual sphere.展开更多
