FACTORS EXPLAINING THE DIFFUSION OF HYBRID MAIZE: EVIDENCE FROM LATIN AMERICA AND THE CARIBBEAN IN SUPPORT OF THE LIFE CYCLE THEORY OF SEED INDUSTRY DEVELOPMENT

Factors affecting the diffusion of hybrid maize are explored using a unique data set from 18 countries in Latin America and the Caribbean. Our findings not only validate the conventional profitability-based explanations of farmer adoption behavior, but also confirm the importance of supply-side factors, providing empirical support for the life cycle theory of seed industry development.Crop Production/Industries,

Urethral Steinstrasse following Laser Lithotripsy of Prostatic Urethral Calculi

Symptomatic prostatic calculi are rare occurrences with several management options, the most popular of which is currently transurethral laser lithotripsy. This is a generally well-tolerated procedure with minimal complications. To date, no reported episodes of steinstrasse at the urethral level following prostatic calculi lithotripsy have been documented to our knowledge. We report a unique case of acute urinary retention secondary to obstructive calculi fragments following a transurethral laser lithotripsy of large prostatic calculi, further complicated by stricture at the fossa navicularis
