单选题If sustainable competitive advantage depends on work-force skills, American firms have a problem. Human resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered as an individual responsibility. Labor is simply another factor of production to be hired or rented at the lowest possible cost much as one buys raw materials or equipment. The lack of importance attached to human resource management can be seen in the corporation hierarchy. In an American firm the chief financial officer is almost always second in command. The post of head of human resource managements is usually a specialized job, often at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer(CEO). By way of contrast, in Japan the head of human resource management is central — usually the second most important executive, after the CEO, in the firm's hierarchy. While American firms often talk about the vast amounts spent on training their work-forces, in fact they invest less in the skill of their employees than do the Japanese or German firms. The money they do invest is also more highly concentrated on professional and managerial employees. And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies. As a result, problems emerge when new breakthrough technologies arrive. If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers in Germany(as they do), the effective cost of those stations is lower in Germany than it is in the United Stated. More time is required before equipment is up and running at capacity, and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be employed. The result is a slower pace of technological change. And in the end the skills of the bottom half of the population affect the wages of the top half. If the bottom half can't effectively staff the processes that have to be operated, the management and professional jobs that go with these processes will disappear.

单选题He didn't do so well in the race ______ his training. A. for all B. above all C. in all D. after all

单选题In England along a stretch of the northeast coast which gently curves from Northumberland to the estuary of the river Tees, there was a spot, typical of many on that coast, where sea coal was collected richly and effortlessly. This coal was a coarse powder, clean and brilliant. It seemed to bear little resemblance to the large, filthy lumps put onto the fire. Although it was coal, it was perfectly clean and it was silently deposited at high tide in a glittering carpet a kilometer long for the local community to gather up. The gear needed for sea-coaling expeditions was a curious and traditionally proven assortment which never varied from community to community along the entire northeast coastline. Sacks were essential to put the coal in, and string to tie the neck of each sack when it is full. A wooden rake was used to scrape the coal from the beach. The only alternative to the rake was a flat piece of board held in the hand. A flat, board shovel to lift the raked coal into the bags, completed the portable hardware. But the most crucial item of equipment was a bicycle, a special kind of rusty striped- down model which was the symbol of the sea-coaling craft. A lady"s bike was no good because it lacked a crossbar, and that was an essential element in transporting sea coal. One full sack could be slung through the triangular frame of a man"s bike, another over the crossbar and, sometimes, even a third on top of that. The beauty of the metal bar against the full, wet sacks forced excess water out of the coal while it was being wheeled home. On a good day, the path to the beach was generally a double snail-track of water that had been forced from each end of a trail of coal sacks.

单选题Forum for the Future, working with Tesco and Unilever, reckon that by 2022 what we buy, how we buy it and who from will have changed radically. In their report, Retail Futures, they look ahead 15 years to see what lies in store for shoppers and the retail groups. They see not only new or bigger store chains, more sprawling retail parks, and more poultry products and pasta sauces. Their visions range from multi- storey car parks converted into city centre allotments or"vertical farms"with produce markets where the parking payment booths once were, to a nation of stay-at-home shoppers who let their fingers do the walking to order in almost everything they need or let their refrigerators do the talking, with automatic, direct-to-store reordering and home delivery every time yoghurt, salad or beer stocks run low. Forum for the Future, a sustainable development charity founded by veteran environmentalist Sir Jonathon Porritt and which now advises more than 100 organizations in the public and private sector, says the reality of 2022 is probably somewhere between the two extremes. "It will be a mixture," said Tom Berry, the Forum's main sustainability adviser. The high street is vital to the economy and the environment: nearly three million people work in retail which generates 6% of UK GDP-- and 2.5% of the country's carbon dioxide emissions. The Forum says stores and retail groups have a disproportionate influence over society as a result of marketing campaigns and daily dealings with consumers. The Forum's researchers identified a range of factors which will affect what we buy, how we buy and who we will buy from in the next 15 years. They include: climate change, which is likely to affect agricultural production, higher- or lower- oil prices, new technology, advances in energy production, more globalization and demographic changes that will mean more immigrant labor and more elderly and single person households. They could prompt new shopping formats, says the Forum, like "Tesco Silver" outlets with customized products for retired baby boomers. They also reckon the bell could be tolling for endless aisles of utility products like toilet paper and bin liners, which might only be sold online, or from a utility section at the back of a store, alongside vast vats of liquids like fabric conditioner, where shoppers could fill reusable containers. The long queue at the checkout could also be history when bar codes are read for prices immediately an item is dropped into a trolley. The online revolution, says the Forum, has only just started: "We can anticipate innovations such as entering your postcode for hyper-local sourcing". Consumers, however, might also use the Internet to cut out the middleman and source direct from farms and manufacturers "so posing a threat to major retailers". The explosion in the number of TV channels and the rise of the Internet to download entertainment means store chains will have to work far harder to build, and keep consumers' trust. One retailer told the researchers: "We won't be able to rely on hitting millions of people at 7:45p.m. on a Wednesday night with a Coronation Street advertising slot." The Forum came up with four different visions of the future depending on high or low economic growth and changing consumer outlooks; whether shoppers want more convenience or to do more for themselves; perhaps buying more locally sourced products with more information about what their families are eating and wearing.

单选题The opposite of adaptive divergence is an interesting and fairly common expression of evolution. Whereas related groups of organisms take on widely different characters in becoming adapted to unlike environments in the case of adaptive divergence. We find that Unrelated groups of organisms exhibit adaptive convergence when they spot similar modes of life or become suited for special sorts of environments. For example, invertebrate marine animals living firmly attached to the sea bottom or to some foreign object tend to develop a sub- cylindrical or conical form. This is illustrated by coral individuals, by many sponges, and even by the diminutive tubes of bryozoans. Adaptive convergence in taking this coral-like form is shown by some brachiopods and pelecypods that grew in fixed position. More readily appreciated is the streamlined fitness of most fishes for moving swiftly through water; they have no neck, the contour of the body is smoothly curved so as to give minimum resistance, and the chief propelling organ is a powerful tail fin. The fact that some fossil reptiles (ichthyosaurs) and modem mammals (whales, dolphins) are wholly fishlike in form is an expression of adaptive convergence, for these air-breathing reptiles and mammals, which are highly efficient swimmers, are not closely related to fishes. Unrelated or distantly related organisms that develop similarity of form are sometimes designated as homeomorphs (having same form).
