单选题In the wake of the Sept. 11 attacks, many Americans feel we may begin to see the erosion of some of our civil liberties. There is concern we may be subject to personal searches and increased monitoring of our activities, all in the name of safety and security. On the computing front, I would argue that we already have had to surrender many of our liberties to protect ourselves from computer viruses and other security breaches. As much as vendors and network administrators try to make scanning for viruses an unobtrusive process for the end user, we still are inconvenienced by the routines mandated by the guardians of our corporate computing security. However, inconvenience takes a back seat to the outright need for security. Viruses are more than inconvenient; they cause real damage. Computer Economics estimates the cost of virus attacks on information systems around the world, including cleanup costs and lost productivity, has already reached $10.7 billion so far this year. Compare that figure with $17.1 billion for all of 2000 and $12.1 billion for 1999. I know you're thinking. "I'm only one person. How can I spend the necessary time to safeguard my company against viruses and security holes and still do my regular job?" Realistically, you can't. But there are resources to help you. Microsoft has just announced a new initiative called the Strategic Technology Protection Program. Among the services being offered are free technical support related to viruses and a security tool kit that includes patches and service packs that address security vulnerabilities in Windows NT and 2000. The FBI and SANS Institute have just released their top 20 list of the most critical Internet security vulnerabilities. The majority of successful attacks on computer systems via the Internet can be traced to exploitation of security flaws on this list. Study the list at www. sanq. org. The Center for Internet Security provides methods and tools to improve, monitor and compare the security status of your Internet-connected systems. Find out how to benchmark your organization's status at www. cisecurity, org. Software vendors such as Network Associates, Symantec and Computer Associates have very informative virus resource centers. The Symantec Antivirus Research Center (www. symantec, com/avcenter) has an online newsletter and in-depth information about viruses. Likewise, the CA Virus Information Center offer tips on managing virus incidents and protecting messaging systems. Just like our national defense, the best protection against a debilitating virus attack is knowledge of the vulnerabilities and the means to plug the security holes. Be proactive and vigilant, and make use of the numerous resources at your disposal.

单选题The rise of multinational corporations, global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR. Surprisingly, since modem PR was largely an American invention, the U. S. leadership in public relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world's top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporate planning activities, compared to about one-third of U. S. companies. It may not belong before London replaces New York as the capital of PR. Why is America lagging behind in the global PR race? Firstly, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, Americans lag behind their European and Asian counterparts in knowing a second language. Less than 5 percent of Burson-Marshall's U. S. employees know two languages. Ogilvy and Mather has about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country. Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable News Network). Turner recently announced that the word "foreign" would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the would so interdependent that there is no longer any such thing as foreign.

单选题To our disappointment, the guide also only has a slight ______ with Italian.

单选题Sometimes, over a span of many Years, a business will continue to grow, generating ever-increasing amounts of cash, repurchasing stock, paying increased dividends, reducing debt, opening new stores, expanding production facilities, moving into new markets, etc., while at the same tune its stock price remains stagnant (or even falls). When this happens, the average and professional investors alike tend to overlook the company because they become familiar with the trading range. Take, for example, Wal-Mart. Over the past five years, the retailing behemoth has grown sales by over 80%, profits by over 100%, and yet the stock price has fallen as much as 30% during that timeframe. Clearly, the valuation picture has changed. An investor that read the annual report back in 2000 or 2001 might have passed on the security, deeming it too expensive based on a metric such as the price to earnings ratio. Today, however, the equation is completely different--despite the stock price, Wal-Mart is, in essence, trading at half its former price because each share is backed by a larger dividend, twice the earnings power, more stores, and a bigger infrastructure. Home Depot is in much the same boat, largely because some Wall Street analysts question how fast two of the world's largest companies can continue to grow before their sheer size slows them down to the rate of the general economy. Coca-Cola is another excellent example of this phenomenon. Ten years ago, in 1996, the stock traded between a range of $36.10 and $54.30 per share. At the time, it had reported earnings per share of $1.40 and paid a cash dividend of $0.50 per share. Corporate per share book value was $2.48. Last year, the stock traded within a range of $40.30 and $45.30 per share; squarely in the middle of the same area it had been nearly a decade prior! Yet, despite the stagnant stock price, the 2006 estimates Value Line Investment Survey estimates for earnings per share stand around $2.16 (a rise of 54%), the cash dividend has more than doubled to $1.20, book value is expected to have grown to $7.40 per share (a gain of nearly 300%), and the total number of shares outstanding (未偿 付的, 未完成的) has actually decreased from 2.481 billion to an estimated 2.355 billion due to the company's share repurchase program.

单选题Every year New Zealanders living in London can be seen loading up Kombi vans and heading off to experience the "classic European holiday". The trip usually starts in the north of France, after crossing the channel from Dover in England to Calais, driving down through France, over the Pyrenees into Spain, west into Portugal and then across the Continent to Italy and often beyond. There are numerous reasons young New Zealanders take this rite of passage—as well as seeing all the fantastic sights and tasting the delights of Europe's food and wine, it's relatively inexpensive. The Kombi is transport and accommodation all in one, cutting down significantly on costs. There is just one problem. As the Kombis become "antique", these trips are usually punctuated with numerous roadside sessions as the van sits idle, in no hurry to start, while you swelter in the hot sun. But do not let this deter you. Travelling Europe in your own vehicle means no public transport schedules to cramp your style, the ability to explore the quaint, off-the-beaten-track villages where the "real" locals live, freedom to not have to book accommodation in advance—you can nearly always get a campsite and can load your vehicle with cheap, fantastic regional wines and souvenirs. With these bonuses in mind, here are some suggestions for planning the great Europe road adventure. The key to a pleasurable driving experience is a good navigator and a driver with a cool head. If you do not feel relaxed driving around New Zealand's cities and highways, then you probably will not enjoy driving around Europe. As copilot to the driver, you need to read (and understand) maps, look out for turn-offs—and keep the music playing. Language is not a big problem once a few essential terms are mastered. The biggest challenge is in the cities, where traffic can be chaotic, and elaborate one-way systems and narrow, cobbled alleyways can make finding your destination hard work. It can be easier to leave the vehicle on the outskirts of town or in a camping ground and use public transport. This also avoids paying for costly parking.
