1 .With speed increasingly seen as the key to competitive advantage, the dream is to marry the control of an established company with the responsiveness of a start-up. As Linda Applegate reports, advances in IT now means that the “big small”company is finally feasible.In the hierarchical companies of the 1960s and 1970s, informaiton moved slowly and channels of communication were limited. Over the past few years, however, large companies have come under ever-increasing pressure to collect, process and distribute information more quickly in order to compete with smaller, more nimble rivals. The key challenge facing any sizeable organisation today is how to achieve responsiveness without losing the control inherent in a hierarchical structure.All types of organisation are controlled through two sets of processes. Operating processes define how a company produces, sells, distributes and supports its products and services. Management processes define how a company directs, coordinates and controls these operations. Typical management processes include planning, budgeting and human resource management.Traditional hierarchical organisiations control operating processes through standardisations of jobs. These jobs are separated into sequential steps and carried out under direct supervision. However, the line workers lack both the authority and motivation to improve these routine tasks and are limited by their local view of the business. Management processes in such companies are also hampered by the time it takes to recognise that change is needed. Thus, hierarchical control is only truly effective in relatively stable business environments where change happens slowly.Entrepreneurial organisations, on the other hand, allow fast response without any loss of control. Daily personal interaction between the owner and employees ensures flexibility and responsiveness, while instant feedback ensures effective control. However, as the company becomes larger and more complex, this control breaks down and more structured operating and management processes required.Information age organisations can manage the complexity of the large hierarchical structure without losing the speed of the entrepreneurial start-up. IT plays a critical role. It coordinates complex fast-cycle operating processes and, more importantly, gives decision-makers quick access to detailed, real-time information about operations and market performance. Once all the information is flowing, employees can quickly evaluate their decisions and continually refine both strategy and operations. Organisational control then becomes a dynamic, information-enabled learning process rather than a static monitoring system.However, although IT makes the “big small” company possible, it can not motivate people to use information in order to act on behalf of the organisation. The challenge for organisation is therefore to ensure that managers and employees share the same perspective on the business and are motivated to accomplish the same goals。

科技英语翻译大作业(科技英语6&13班)I.全篇翻译passage1：Passage１Billing for goods and services that customers have purchased is part of any business. Traditional billing methods in the brick-and-mortar paradigms are costly and involve generating invoices, stuffing envelopes, affixing proper postage to the envelopes, and sending the invoices to the customers. Meanwhile, the accounts payable department must keep track of incoming payments, post accounts in the database, and ensure that customer data are current.Online stores have many of the same payment collection inefficiencies as their brick-and-mortar cousins. Most online customers use credit cards to pay for their purchases, while auction customers may also use conventional payments methods, including checks and money orders. Electronic cash systems, though less popular than other payment methods do provide several advantages as well as some disadvantages unique to electronic cash.For the most part, electronic cash transactions aremore efficient (and therefore less costly) than other methods, and that should foster more business, which eventually means lower prices for consumers. Transferring electronic cash on the Internet costs less than processing credit card transactions. You have observed that conventional money exchange systems require banks, banks branches, clerks, automated teller machines, and a parallel electronic transaction system to manage, transfer and dispense cash. That is expensive. On the other hand, electronic cash transfers occur across an existing infrastructure, the Internet, and through existing computer systems. So the fixed cost of hardware to handle electronic cash is nearly zero. Because the Internet spans the globe, the distance that an electronic transaction must travel does not affect cost. When considering moving physical cash and checks, distance and cost are proportional---the greater the distance that the currency has to go, the more it costs to move it. However, moving electronic currency from Detroit to San Francisco costs the same as moving it from San Francisco to Hong Dong. Everyone can use electronic cash. Merchants can pay other merchants ina business-to-business relationship, and consumers can pay each other. Electronic cash does not require that one party have any special authorization, as is required with credit card transactions. (345 words)II.请翻译passage 2中带有下划的5个句子：Passage２1) Anxiety may be the most common mental disorder experienced by older adults, affecting one in 10 people over the age of 60, according to research presented at the Annual Meeting of the American Psychiatric Association in Toronto. Despite its prevalence, anxiety remains one of the most undiagnosed and undertreated conditions in this population.Examples of anxiety disorders include panic disorder, obsessive compulsive disorder, phobias and generalized anxiety disorder (GAD). GAD is characterized by exaggerated, uncontrollable worries about everyday things. 2) While many worrisome events occur as people age and while it is normal for people to be concerned about such things as deteriorating health and financial troubles, people with GAD tend to worry excessivelyand constantly.3) “Studies have shown that generalized anxiety disorder is more common in the elderly, affecting seven per cent of seniors, than depression, which affects about three per cent of seniors. Surprisingly, there is little research that has been done on this disorder in the elderly,” said Eric J. Lenze, M.D., assistant professor of psychiatry, University of Pittsburgh School of Medic ine. “Doctors often think that this disorder is rare in the elderly or that it is a normal part of aging, so they don’t diagnose or treat anxiety in their older patients, when, in fact, anxiety is quite common in the elderly and can have a serious impact o n quality of life.”This constant level of worry can have negative, and sometimes even disabling, effects on a person’s life. Many people with GAD have trouble sleeping or limit their daily activities due to their anxiety. 4) Untreated anxiety can also lead to anxious depression – a condition that is more difficult to treat and carries a higher risk of suicide than depression.“Anxiety in people over age 60 might has some similarities to anxiety in those younger, but it also hasmarked differences. We ca n’t just assume that we can treat the two age groups the same,” said Dr. Lenze. 5) “We are decades behind where we need to be in terms of research and treatments for anxiety in this older age group.” There are, however, encouraging signs that studies are beginning to address treatment options. What It Means: Anxious older adults and their families should be aware of the prevalence of anxiety disorders. Excessive fretting should not be considered an inevitable sign of aging. A small pilot study conducted at the University of Pittsburgh has shown that ananti-depressant drug was also effective in treating anxiety in older adults. Additional studies hope to address the role of cognitive behavioral therapy or other therapies for anxiety in the elderly. There are indeed enough things to worry about when growing older. But uncontrollable, excessive worry shouldn’t be among them. (453 words)。
