红叶超级市场营业面积260平方米，位于居民聚集的主要街道上，附近有许多各类商场和同类超级市场。营业额和利润虽然还过得去，但是与同等面积的商场相比，还是觉得不理想。通过询问部分顾客，得知顾客认为店内拥挤杂乱，商品质量差档次低。听到这种放映，红叶超市经理感到诧异，因为红叶超市的顾客没有同类超市多，每每看到别的超市人头攒动而本店较为冷清，怎会拥挤呢？本店的商品都是货真价实的，与别的超市相同，怎说质量差档次低呢？经过对红叶超市购物环境的分析，发现了真实原因。原来，红叶超市为了充分利用商场的空间，柜台安放过多，过道太狭窄，购物高峰时期就会造成拥挤，顾客不愿入内，即使入内也不易找到所需的商品，往往是草草转一圈就很快离去；商场灯光暗淡，货架陈旧，墙壁和屋顶多年没有装修，优质商品放在这种背景下也会显得质量差档次低。为了提高竞争力，红叶超市的经理痛下决心，拿出一笔资金对商店购物环境进行彻底改造。对商店的地板、墙壁、照明和屋顶都进行了装修；减少了柜台的数量，加宽了走道，仿照别的超市摆放柜台和商品，以方便顾客找到商品。整修一新开业后，立刻见到了效果，头一个星期的销售额和利润比过去增加了70%。可是随后的销售额和利润又不断下降，半个月后降到了以往的水平，一个月后低于以往的水平。为什么出现这种情况呢？观察发现，有些老顾客不来购物了，增加了一批新顾客，但是新增的顾客没有流失的老顾客多。对部分顾客的调查表明，顾客认为购物环境是比原先好了，商品档次也提高了，但是商品摆放依然不太合理，同时商品价格也提高了，别的商店更便宜些，一批老顾客就到别处购买了。听到这种反映，红叶超市的经理再次感到诧异，因为一般来说，红叶超市装修后商品的价格并未提高，只是调整了商品结构，减少了部分微利商品，增加正常利润和厚利商品，其价格与其他超市相同。

究竟怎样才能适应顾客呢？

红叶超市原先的购物环境导致顾客对其所售商品怎样的认知？装修后的购物环境导致顾客怎样的认知？

Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound experience in the summer of 1980, when he participated in the NASA-AS-EE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point, was assigned to the Marshall Space Flight Center’s propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seals could have led to destructive results for the astronauts who relied on them.

"I worked a bit with NASA engineers," says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic analysis. "At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall, summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status.

It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1978. Over the next nine years he reapplied repeatedly, and was finally accepted in 1987. Since then he has participated in three space missions. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000.

Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes link with our colleges and universities," Voss explains. "There’s an exchange of information and an exchange of perspectives that is very important."

For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom. \

A. Three

B. Two
