在基于数据的生产者消费者结构中,关于队列,下面描述不正确的是
A、当队列中数据达到设定值(如1024个);“进入队列”的线程被动等待,直到队列中有别的线程取出数据,使队列出现空闲位置,才会让新数据入队。但出现空闲之前的入队数据会丢失。
B、队列同数据缓冲区类似,是一个先入先出(FIFO)的数据结构
C、若出队速度大于入队速度,队列中不会有多余数据
D、队列具有调节读写速度的能力

B.构建场景是给受众制造一个与产品或品牌相关的场景想象或场景联想,让受众下一次在相同或类似的场景下触景生情而联想到该产品或品牌,从而传达品牌的定位或价值,并提供产品销售或使用率。
C.以用户体验为核心,走进消费者的生活和工作场景,并模拟这些场景,包括购买场景、使用场景、工作场景与生活场景,去发现痛点,寻找机会点,然后设计产品、服务和特定的体验场景。
D.场景构建例子: 西贝筱面村发现:孩子不爱吃饭,家长不会做饭。家长的亲子时光太少——这是痛点。西贝根据行业特点,特别设置了“做饭”的两个场景,来提供解决方案。 A.亲子私房菜课程——家长报名,带着孩子跟西贝大厨一起学做菜。
B.儿童搓筱面比赛——给孩子报名,孩子们和其他小朋友一起玩,一起社交,一起比赛。 无论是跟着大厨学做菜,还是孩子们比赛搓筱面,一经推出,效果火爆:亲子私房菜周周抢购!为什么,有体验、有娱乐、有温度、有社交。都是谁来购买?可以是家长——购买后周末带着家人、孩子一起到西贝体验烧菜,同时享受亲子时光;也可以送亲友——增加与亲友的情感连接;甚至一些单位也来购买,单位主要作为福利送员工或者顾客,体现单位的人性化关怀。 尤其是亲子私房菜课程,还有一些意外收获:卖厨具、卖食材。因为学习了私房菜,很多家庭希望买到和西贝一样的厨具和食材。结果,西贝的厨具和食材也开始旺销。

Jackson Specialties has been in business for more than 50 years. The company maintains a perpetual inventory system, uses a LIFO flow assumption, and ends its fiscal year at December 31. At year-end, the cost of goods sold and inventory are adjusted to reflect periodic LIFO costing procedures. A railroad strike has delayed the arrival of purchases ordered during the past several months of 2011, and Jackson Specialties has not been able to replenish its inventories as merchandise is sold. At December 22, one product appears in the company's perpetual inventory records at the following unit costs: Purchase Date Quantity Unit Cost Total Cost Nov. 14, 1958 ................................ 3,000 $6 $18,000 Apr. 12, 1959 ................................ 2,000 8 16,000 Available for sale at Dec. 22,2011 5,000 $34,000 Jackson Specialties has another 8,000 units of this product on order at the current wholesale cost of $30 per unit. Because of the railroad strike, however, these units have not yet arrived (the terms of purchase are F.O.B. destination). Jackson Specialties also has an order from a customer who wants to purchase 4,000 units of this product at the retail sales price of $47 per unit. Jackson Specialties intends to make this sale on December 30, regardless of whether the 8,000 units on order arrive by this date. (The 4,000-unit sale will be shipped by truck, F.O.B. shipping point.) Instructions a. Are the units in inventory really more than 50 years old? Explain. b. Prepare a schedule showing the sales revenue, cost of goods sold, and gross profit that will result from this sale on December 30, assuming that the 8,000 units currently on order ( 1 ) arrive before year-end and (2) do not arrive until some time in the following year. (In each computation, show the number of units comprising the cost of goods sold and their related per-unit costs.) c. Comment on these results. d. Might management be wise to delay this sale by a few days? Explain.
