Note: When more than one answer is required, these may be given in any order. Some choices may be required more than once. A=Nokia B=Ericsson C=Philips D=Siemens E=Motorola Which mobile phone(s) ... · has a small and complex keyboard and screen 21. ______ · has combined handwriting and keying 22. ______ · can recognize voices 23. ______ · has a voice dial tag 24. ______ · has a pen which can write in the air 25. ______ · might carry out financial transactions 26. ______ · are working on dual slot phones 27. ______ 28. ______ · can be connected to your home by a saying’Home’ 29. ______ · is both a phone and personal digital assistant 30. ______ Once the exclusive domain of executives with expense accounts, the mobile phone is set to become one of the central technologies of the 21st century. Within a few years, the mobile phone will evolve from a voice-only device to a multi-functional communicator capable of transmitting and receiving not only sound, but video, still images, data and text. A whole new era of personal communication is on the way. Thanks in part to the growth of wireless networks, the telephone is converging with the personal computer and the television. Soon lightweight phones outfitted with high-resolution screens -which can be embedded in everything from wristwatches to palm-held units -will be connected to series of low orbit satellites enabling people to talk, send and receive e-mail, or take part in video conferences anytime, anywhere. These phones might also absorb many of the key functions of the desktop computer. Mobile devices are expected to be ideal for some of the new personalized services that are becoming available via the Internet, such as trading stocks, gambling, shopping and buying theater and airline tickets. The communications revolution is already taking shape around the globe. In Europe, small-scale trials are under way using mobile phones for electronic commerce. For example, most phones contain a Subscriber Identification Module (SIM) card that serves primarily to identify a user to the phone network. But the card could also facilitate limited financial transactions. Deutsche Bank and Nokia, for example, are working together to develop mobile banking services. Some manufacturers plan to upgrade the SIM card to an all-in-one personal identification and credit card. Another approach is to add a slot to mobile phones for a second smart card designed specifically for mobile e-commerce. These cards could be used to make payments over the Internet or removed from the phone for use in point-of-sale terminals to pay for things like public transportation, movie tickets or a round of drinks at the bar. In France, Motorola is currently testing a dual slot phone, the StarTACD, in a trial with France Telecom, while in Finland Nokia is testing a phone that uses a special plug-in reader for a tiny smart card. Siemens is pursuing a different approach. Since it is not yet clear whether it’s best to do everything with a single device, Siemens is developing dual slot phones and Einstein, a device equipped with a smart card reader and keypad that can be linked to the phone via infrared wireless technology. For those who want to, though, it will be possible to receive almost all forms of electronic communication through a single device, most likely a three-in-one phone that serves as a cordless at home, a cell phone on the road and an intercom at work. "The mobile phone will become increasingly multifunctional," says Burghardt Schallenberger, vice president for technology and innovation at Siemens Information and Consumer Products in Munich, "and fingerprint technology or advanced speech recognition will ensure that only one or two authorized users will be able to operate it." New hybrid devices, such as Nokia’s 9110 Communicator, a combination phone and personal digital assistant (P.D.A.), are already on the market. But some customers feel the keyboard and screen are too small and complex for comfort. To get around these problems, Nokia’s 7110 mobile phone has a larger screen and is operated by a tracking ball in addition to a keyboard. The phone has found a ready market among young people, who tend to send more text messages than they make mobile phone calls not surprising given the fact that text is approximately a tenth as costly as voice. The Nokia 7110 also offers Internet access via Wireless Application Protocol (WAP), an open standard that allows streamlined versions of website contents to be displayed on mobile phone screens. Phones equipped -with WAP enable people on the move to access basic information such as news services, stock prices and flight timetables from specially -"cut-down" sites. For some, any device that bridges the gap between handwriting and keying in text will be a world-beater. Ericsson is researching a "smart quill" pen that could do just that. Though the smart quill looks like any other pen, it permits writers to write on any surface -or even in the air -while a microchip in the tip of the pen records the shape of the scribblings and transmits them to a remote PC, where special software converts them into normal text. Could this mean the end of typing Not yet. Ericsson cannot say when a prototype will be ready. Keyboards might eventually be unnecessary on mobile handsets if speech recognition software continues to improve. Mobile phones might then be reduced to a few computer chips, a microphone and a receiver embedded in an earring. The Philips Genie, a lightweight mobile phone, can be operated by uttering a single word. When you type a name into the Genie’s keypad, the system asks whether you would like to assign a voice-dial tag to that name. Through a series of yes or no prompts, the Genie compiles a list of up to 10 voice tags. The next time you want to call a person listed as one of these tags, just say that person’s name or a relevant code word. The word home, for example, is sufficient to place a call to your family.

The new-technology revolution in American newspapers has brought increased circulations, a wider range of publications and an expansion of newspaper jobs in spite of reduced manning in the composing rooms. Payrolls in the publishing industry more than doubled in a decade from $3.1 billion in 1972 to $6.3 billion in 1981. Capital investment, largely as a result of re-equipment with new technology, doubled from $554m in 1972 to $1.02 billion in 1981. Circulation of weekly newspapers has grown from 21m in 1960 to 49m in 1985. Big city dailies have remained relatively static, with total circulation going from 58m to 63m. Sunday papers, though, have grown more dramatically from 8.6m to 56m. This reflects the trend toward specialisation. Growth has been especially strong in the number and circulation of suburban and small-community newspapers. In 1965 there were only 357 semi-weekly papers; in 1982, 508. There has also been a dramatic rise in newspapers circulating nationwide something that hardly existed in the old days. The Wall Street Journal is producing regional editions that have catapulted it into becoming the nation’s largest-circulation newspaper, a role formerly held by the New York Daily News. In addition, USA Today and the New York Times have used technological advances, particularly satellite-delivery of pages to regional production facilities, to achieve unprecedented growth. A number of daily papers have added Sunday editions -made possible through the new technology in response to demand from advertisers. Total newspaper employment, according to government statistics, rose from 345,000 in 1965 to 443,000 in 1984 and that figure does not fully cover the multitude of local papers. But the International Typographical Union, which formerly had a firm grip on nearly all printing jobs, has shrunk from over 100,000 in 1967 to 40,000 today, of whom about 4,000 are in fact retired members. The prospect is that the union may be reduced to 5,000 members in the near future. According to Jim Cesnik of the 33,000-member journalists’ union, the Newspaper Guild, employment of journalists has grown but not to the same extent as that of sales people pushing advertising and circulation. The guild, however, has few members on the small local papers. The New York Times spent $2m on radio advertising to boost home-delivery of the paper in the first nine months of 1985 -a campaign responding to a fall in the number of streetside news-stands. The general growth in circulations has helped increase advertising revenue among dailies from $15 billion in 1965 to $66 billion in 1982. An interesting development noted by Charles Cole, a consultant to the 1,375-member American Newspaper Publishers Association, is that local newspapers have expanded their news-gathering teams, and some now send people abroad as well as having representatives in many American cities. Other departments in papers have also advanced, according to Cole. For example, mail rooms of many newspapers employ up to 25% more people handling the national advertising inserts that have become common. However, more automatic machinery may well reduce manning here. Which of the following has grown most rapidly in number

A new variety of sugar cane, bred from crosses of ordinary cultivated strains with a wild type found in Argentina, could become an important source of energy as well as sugar. Two conditions need to be fulfilled to make it worthwhile to cultivate an agricultural crop for energy. The crop must be easy to harvest and process, and it must be high-yielding. On both these counts, sugar cane is ideal: the technology for harvesting and milling has been thoroughly tested over the years, and sugar cane is one of the most productive plants ever recorded. Professor Mike Giamalva and his colleagues at Louisiana State University have now produced a plant that is super-productive. Their new variety grows to 3.6 metres high. On experimental plots, it gives yields of 253 tons per hectare -equal to the highest yield of any plant recorded. But even this record has been exceeded. On good soil, yields may reach 321 tons per hectare. Another advantage of Giamalva’s new strain of sugar cane is its high fibre content. Traditionally, researchers have selected strains that produce large amounts of juice rich in sugar, and low quantities of fibre. The fibre is either discarded, or sometimes burnt as fuel. The new sugar cane gives exceptional quantities of fibre for only modest amounts of juice. When it comes from the mill, the bagasse has about 70 per cent of the heat content of wood, or 30-40 per cent of that of coal. Burning bagasse to provide energy is not a new idea. Many sugar factories throughout the world are now self-sufficient in energy, while some, for example, in Mauritius, Hawaii and South Africa, "export" electricity to the national grid. Mauritius currently gets around 10 per cent of its electricity from sugar factories. However, in Louisiana local farmers are unwilling to grow the cane until they have a guaranteed market. Yet industrialists will not invest in the new fuel until they have a constant supply. And only local factories may be able to exploit cane because, being bulky, it is costly to transport. One way of overcoming this problem would be to dry the fibrous residue and compact it. Work on compacting fibrous residue is now under way in several research centres. Whether compacting will pay its way will depend on the local situation and the cost of alternative energy supplies. A study carried out by Fay Baguant from the University of Mauritius showed that electricity could be produced there from fibrous residue about twice as cheaply as from oil or coalfired stations. The new variety can be grown with ordinary sugar cane or with other crops to provide energy for processing. It can be compressed and burned as a substitute for charcoal. Or it can be incorporated into paper, cardboard and fibreboard. Brazil, with its fleet of cars running almost entirely on alcohol fuel extracted from sugar cane, already has shown that the plant has the potential to alter radically a country’s agricultural sector.
