Inspection Accuracy vs. Speed
所謂檢驗準確度 (Inspection Accuracy)包含兩項指標：
1. 將不良品判定為良品的機率
2. 將良品判定為不良品的機率
許多研究顯示﹐當檢驗速度增加時﹐往往兩種錯誤都會增加。但亦非越慢之檢驗可得到越準確之檢驗結果。根據Drury(1973)的研究 "The effect of Speed of Working on Industrial Inspection Accuracy." 當檢驗時間延長後﹐雖然可以提高不良品被驗出之機會﹐卻也提高了良品被判定為不良品的機會。這可能與檢驗員在延長檢驗時間後﹐覺得自己應改有所"貢獻"的心態有關。

"Effect"
這標題很複雜 或許可再深入討論
譬如說 美國最進M州的橋垮下來
它的檢驗報告都未提出"嚴重性"警告
這是本案調查之重點之一
我昨天幫某書匆匆作一勘誤表
還是提出許多上回讀沒注意的問題
哈哈
呼應最後說的

Beijingers were outraged by a report released on July 8th that claimed that street vendors were using cardboard soaked in chemicals to augment the filling in their meat buns. Originally aired on Beijing Television, and later picked up by China Central Television, the “exposé” came amid global concerns over the safety standards under which Chinese food, medicines and other products for export are manufactured. New outrage exploded ten days later when Beijing Television announced that the report was fake. Zi Beijia, the freelance journalist behind it, has been detained by police. State media have said that Mr Zi felt pressure to produce an eye-catching report after monitoring a bun store for two weeks and seeing nothing suspicious. For background, see article
