Smith was a pioneer epidemiologist, bacteriologist, and pathologist who made many contributions to medical science that were of far-reaching importance. He is best known for his work on Texas cattle fever, in which he and his colleagues discovered the protozoan agent and its means of transmission by ticks. This was the ¿ rst time that an arthropod had been de¿ nitively linked with the transmiss...

ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...

In an open-ended contingent valuation (CV) survey, a respondent can state any non-negative valuation for a given good. As the set of possible responses is infinite, the GibbardSatterthwaite theorem implies that such a survey cannot be incentive-compatible. That is, participants in an open-ended CV survey have an incentive to increase their utility by misrepresenting their preferences. This natu...

In this study, Black, Macklem, and Rose thoroughly describe the outcomes when a wide range of reaction functions are set in CPAM, the Canadian Policy Analysis Model developed at the Bank of Canada. The reaction functions for monetary policy influence the short-term interest rate relative to the long-term rate. The analysis begins with the CPAM reaction function, which targets the expected diffe...

breeding based on selection indices is an effective method for improving complex traits such as yield. to assess the efficiency of different selection methods, 50 genotypes of tall fescue (festuca arundinace) were evaluated under two moisture conditions including full irrigation (normal environment) and deficit irrigation (stress environment). the experiment was conducted according to a randomi...

“We need not be surprised … that the Cartesian philosophy …, though it does perhaps contain a word of truth, should nevertheless have been so universally received by all Learned in Europe at time. [They] greedily receive[d] work which we justly esteem one most entertaining Romances has ever wrote.” LRBL ii.134
