The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

Agribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Stonehenge as an Astronomical Instrument [PDF]

Antiquity, 1927
The astronomical controversy about Stonehenge may perhaps be approached from an impartial view of one who is neither an archaeologist nor an astronomer, who offers no new or original observations, and proposes to examine facts rather than to discuss theories.Sir Norman Lockyer was one of those who held that many Egyptian and Greek buildings were set so
