    PV Co is evaluating an investment proposal to manufacture Product W33, which has performed well in test marketing trials conducted recently by the company’s research and development division. The following information relating to this investment proposal has now been prepared.

    Initial investment $2 million

    Selling price (current price terms) $20 per unit

    Expected selling price inflation 3% per year

    Variable operating costs (current price terms) $8 per unit

    Fixed operating costs (current price terms) $170,000 per year

    Human Heart can Make New Cells

    Solving a longstanding(为时甚久的)mystery, scientists have found that the human heart continues to
    generate new cardiac(心脏的)cells throughout the life span, although the rate of new cell production slows
    with age.
    The finding,published in the April 3rd issue of Science,could open a new path for the treatment of heart
    diseases such as heart failure and heart attack,experts say.
    "We find that the beating cells in the heart, cardiomyocytes(心肌细胞),are renewed," said lead
    researcher Dr. Jonas Frisen,a professor of stem cell research at the Karolinska Institute in Stockholm,
    Sweden."It has previously not been known whether we were limited to the cardiomyocytes we were born with
    or whether they could be renewed,"he said.
    "The process of renewing these cells changes over time,"Frisen added. In a 20-year-old,about 1
    percent of cardiomyocytes are exchanged each year , but the turnover(更替)rate decreases with age to only
    0.45 percent by age 75.
    "If we can understand how the generation of new cardiomyocytes is regulated,it may be potentially
    possible to develop pharmaceuticals(药物)that promote this process to stimulate regeneration after , for
    example,a heart attack,"Frisen said.
    That could lead to treatment that helps restore damaged hearts.
    "A lot of people suffer from chronic heart failure,."noted co-author Dr. Ratan Bhardwaj,also from the
    Karolinska Institute."Chronic heart failure arises from heart cells dying," he said.
    "With this finding,scientists are opening the door to potential therapies(疗法),to having ourselves heal
    ourselves,"Bhardwaj said."Maybe one could devise a pharmaceutical agent that would make heart cells
    make new and more cells to overcome the problem they are facing."
    But barriers remain.According to Bhardwaj,scientists do not yet know how to increase heart cell
    production to a rate that would replace cells faster than they are dying off,especially in older patients with
    heart failure.In addition,the number of new cells the heart produces was estimated using healthy hearts一
    whether the rate of cell turnover in diseased hearts is the same remains unknown.

    It is not known yet if the rate of cell turnover in diseased hearts_________.
    A:is high enough to replace cells faster than they're dying off
    B:is of any use to researchers
    C:is the same as that in healthy hearts
    D:changes over time

    答案:C
    解析:
    根据第一段中“…the human heart continues to generate new cardiac(心脏的)cells throughout the life span”可知,在人的整个生命进程中,其心脏持续产生新的心肌细胞。言外之 意,这个过程直到生命结束才会停止。
    根据第二段中“The finding...could open a new path for the treatment of heart diseases”可 知,这个研究成果将为心脏病的治疗开辟新的途径。因此C项符合题意。
    根据第四段中“…but the turnover(更替)rate decreases with age to only 0.45 percent by age 75”可知,C项符合题意。
    根据倒数第三段中“Chronic heart failure arises from heart cells dying”可知,慢性心力衰 竭是由心肌细胞死亡导致的。因此A项符合题意。
    最后一句的大意是:另外,心脏产生的新细胞的数量是按照健康心脏估算的,而患病心脏的细胞更替率是否与健康心脏相同还不得而知。因此C项符合题意。第二篇 本篇文章主要讲述了远古冰人尸体的发现及对其的相关研究情况。

    Big Cheese Chairs (BCC) manufactures and sells executive leather chairs. They are considering a new design of massaging chair to launch into the competitive market in which they operate.

    They have carried out an investigation in the market and using a target costing system have targeted a competitive selling price of $120 for the chair. BCC wants a margin on selling price of 20% (ignoring any overheads).

    The frame. and massage mechanism will be bought in for $51 per chair and BCC will upholster it in leather and assemble it ready for despatch.

    Leather costs $10 per metre and two metres are needed for a complete chair although 20% of all leather is wasted in the upholstery process.

    The upholstery and assembly process will be subject to a learning effect as the workers get used to the new design.

    BCC estimates that the first chair will take two hours to prepare but this will be subject to a learning rate (LR) of 95%.

    The learning improvement will stop once 128 chairs have been made and the time for the 128th chair will be the time for all subsequent chairs. The cost of labour is $15 per hour.

    The learning formula is shown on the formula sheet and at the 95% learning rate the value of b is -0·074000581.

    Required:

    (a) Calculate the average cost for the first 128 chairs made and identify any cost gap that may be present at

    that stage. (8 marks)

    (b) Assuming that a cost gap for the chair exists suggest four ways in which it could be closed. (6 marks)

    The production manager denies any claims that a cost gap exists and has stated that the cost of the 128th chair will be low enough to yield the required margin.

    (c) Calculate the cost of the 128th chair made and state whether the target cost is being achieved on the 128th chair. (6 marks)


    正确答案:

    (W1)
    The cost of the labour can be calculated using learning curve principles. The formula can be used or a tabular approach would
    also give the average cost of 128 chairs. Both methods are acceptable and shown here.

    (b) To reduce the cost gap various methods are possible (only four are needed for full marks)
    – Re-design the chair to remove unnecessary features and hence cost
    – Negotiate with the frame. supplier for a better cost. This may be easier as the volume of sales improve as suppliers often
    are willing to give discounts for bulk buying. Alternatively a different frame. supplier could be found that offers a better
    price. Care would be needed here to maintain the required quality
    – Leather can be bought from different suppliers or at a better price also. Reducing the level of waste would save on cost.
    Even a small reduction in waste rates would remove much of the cost gap that exists
    – Improve the rate of learning by better training and supervision
    – Employ cheaper labour by reducing the skill level expected. Care would also be needed here not to sacrifice quality or
    push up waste rates.
    (c) The cost of the 128th chair will be:

    A pharmaceutical company tested a new painkiller on 1,000 lab rats that were fed large doses of the painkiller for a two-month period. By the end of the experiment, 39 of the rats had died. The company concluded that the painkiller was sufficiently safe to test on humans.  Which of the following, if true, provides the most support for the pharmaceutical company’s conclusion?
    A

    The amount of painkiller fed to the rats was substantially greater, in relation to body mass, than the dosage any human would take under normal circumstances.

    B

    Because of the different body chemistry of humans and rats, some compounds can be dangerous for rats but safe for humans, and vice versa.

    C

    Tests of this same painkiller on dogs showed that 3 out of 50 dogs developed lesions on their livers during the course of the experiment.

    D

    The researchers found that during the experiment, the rats showed a significantly lower sensitivity to pain than rats do under normal circumstances.
