105.As the administrative manager in a law office, you have been asked to develop a system for evaluating the productivity of the 15 lawyers in the office. What difficulties are you going to have in doing this, and how are you going to overcome them?

Productivity measurers for a law office are difficult. Simple criteria, like number of cases processed, fail to consider complexity of the case. Even counting wins is difficult, as many cases are settled with some sort of compromise. External elements such as the quality of the opposing counsel and the tenacity of the opposition also make counting look rather silly.

Categories of cases can help—(i.e., uncontested divorce, no personal injury auto case, etc.) How ever, many firms end up counting hours billed. This in turns leads to other problems, as noted by the number of false billing cases. (The productivity challenge, moderate)

112.The Dulac Box plant produces wooden packing boxes to be used in the local seafood industry.

Current operations allow the company to make 500 boxes per day, in two 8-hour shifts (250 boxes per shift). The company has introduced some moderate changes in equipment, and conducted

appropriate job training, so that production levels have risen to 300 boxes per shift. Labor costs average $10 per hour for each of the 5 full-time workers on each shift. Capital costs were

previously $3,000 per day, and rose to $3,200 per day with the equipment modifications. Energy costs were unchanged by the modifications, at $400 per day. What is the firm's multifactor

productivity before and after the changes?

MFP before: 500 boxes / ($10x5x16 + $3000 + $400) = 500 / 4200 = 0.119 boxes/dollar

MFP after: 600 boxes / ($10x5x16 + $3200 + $400) = 600 / 4400 = 0.136 boxes/dollar

(The productivity challenge, moderate)

113.Gibson Products produces cast bronze valves for use in offshore oil platforms. Currently, Gibson produces 1600 valves per day. The 20 workers at Gibson work from 7 a.m. until 4 p.m., with 30 minutes off for lunch and a 15 minute break during the morning work session and another at the afternoon work session. Gibson is in a competitive industry, and needs to increase productivity to stay competitive. They feel that a 20 percent increase is needed.

Gibson's management believes that the 20 percent increase will not be possible without a change in working conditions, so they change work hours. The new schedule calls on workers to work from 7:30 a.m. until 4:30 p.m., during which workers can take one hour off at any time of their choosing.

Obviously, the number of paid hours is the same as before, but production increases, perhaps

because workers are given a bit more control over their workday. After this change, valve

production increased to 1800 units per day.

a. Calculate labor productivity for the initial situation

b. Calculate labor productivity for the hypothetical 20 percent increase

c. What is the productivity after the change in work rules?

d. Write a short paragraph analyzing these results.

(a) Workers are active for eight hours per day; labor productivity is 10 valves/hour

(b) Productivity rises by 20 percent, to 12 valves/hour; output will be 12x8x20 = 1920

(d) Gibson did not gain the desired 20 percent increase in productivity, but they did gain over

ten percent, without extra equipment or energy, and without increasing the wage bill.

Reading Comprehension (2’X20=40’) Directions: Read the following three passages carefully and do the multiple-choice questions. Passage One Dogs are social animals and without proper training, they will behave like wild animals. They spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong things. The key to preventing or treating behavior problem is learning to teach the dog to redirect its normal behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of “come here, sit”, it is showing obedience and respect for you. It is necessary to establish yourself as top dog or leader of the dog pack by using extreme measures. You can teach your dog its subordinate role by teaching it to show submission to you. Most dogs love performing tricks for you pleasantly if they accept that you are in charge. Tainting should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and more safely allowed a greater amount of freedom than an untrained animal. 1. Behavior problems of dogs are believed to _______. A) worsen in modern society B) be just part of their nature C) occur when they go wild D) present at threat to the community 2. The primary purpose of obedience training is to ________. A) enable the dog to regain its normal behavior B) teach the dog to perform clever tricks C) make the dog aware of its owner’s authority D) provide the dog with outlets for its wild behavior 3. Effective communication between a dog and its owner is _______. A) an extreme measure in obedience training B) a good way to teach the dog new tricks C) the foundation for dogs to perform tasks D) essential to solve the dog’s behavior problems 4. Why do pet dogs love performing tricks for their masters? A) To show their willingness to obey. B) To show their affection for their masters. C) To avoid being punished. D) To win leadership of the dog pack. 5. When a dog has received effective obedience training, its owner________. A) will enjoy a better family life. B) can give the dog more freedom C) can give the dog more rewards D) will have more confidence in himself Passage Two: Once upon a time there was a wise man that used to go to the ocean to do his writing. He had a habit of walking on the beach before he began his work. One day he was walking along the shore. As he looked down the beach, he saw a human figure moving like a dancer. He smiled to himself at the thought of someone who would dance on the beach. So he began to walk faster to catch up. As he got closer, he saw that it was a young man and the young man wasn't dancing, but instead he was reaching down to the shore, picking up something and

Part 7 Reading Comprehension (Multiple Choice) (每小题：1 分) Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D. Questions 1 to 5 are based on the same passage or dialog. One phase of the business cycle is the expansion phase. This phase is a two-fold one, including recovery and prosperity. During the recovery period there is ever-growing expansion of existing facilities, and new facilities for production are created. More businesses are created and older ones expanded. Improvements of various kinds are made. There is an ever increasing optimism about the future of economic growth. Much capital is invested in machinery or heavy industry. More labor is employed. More raw materials are required. As one part of the economy develops, other parts are affected. For example, a large expansion in automobiles results in an expansion of the steel, glass, and rubber industries. Roads are required; thus the cement and machinery industries are stimulated. Demand for labor and materials results in greater prosperity for workers and farmers from increased demand for supplies of raw materials. This increases purchasing power and the volume of goods bought and sold. Thus prosperity is diffused (扩散) among the various segments of the population. This prosperity period may continue to rise and rise without an apparent end. However, a time comes when this phase reaches a peak and stops spiraling (盘旋上升) upwards. This is the end of the expansion phase. 1.We may assume that in the next paragraph the writer will discuss ________. A. the expansion phase B. the status of the farmer C. the higher cost of living D. the recession period 2.The title below that best expresses the ideas of this passage is ________. A. Attaining Prosperity in One Industry
