'>Mothers and matchmakers have always known that not being monied is a definite health hazard. But when a team of research from the University of California, San Francisco, reported a few weeks ago that middle-aged men without wives were actually twice as likely to die during a 10-year span as men with wives, the espoused and the spouseless alike stopped to take notice. It was the kind of news that swept through offices and watering holes — and it made people feel smug and anxious, depending on their circumstances. Now the researchers who conducted the study are trying to find out what accounted for the dramatic differences in survival rates.The investigators, headed by UCSF associate professor of epidemiology and biostatistics Maradee A. Davis, had set cut to examine the effect of various living arrangements on mortality. Because of the buttering social support marriage is known to provide. Davis and her colleagues fully expected to find that men and women dwelling alone fared worst in survival rates. It came as some surprise, however, that in their study population, subjects who shared living quarters with people other than a spouse had the same lower survival rates as those who lived by themselves."The critical factor," Davis says, "seems to be the presence of a spouse."The lower survival rates for the spouseless were found primarily in men who were widowed, separated or divorced, rather than in those who had never been married. Davis and her colleagues have already eliminated certain health factors as causes of higher mortality by adjusting their data to discount the effects of smoking, alcohol consumption, obesity and lack of exercise. Now they will look more closely at a variety of other considerations, such as blood pressure, cholesteric levels and chronic illnesses.While many middle-aged men now know the difference between a cheese grater and a garlic press, nutrition may still account for some of the California study's findings. Previous research by Davis' team showed that unmarried man-even if they lived with other people—ate less healthy diets

'>The function of the office is to perform administrative work. First, it must provide the necessary communications with customers, banks, governments, and other outside organizations. Second, it must service the information requirements within the company itself. In order to meet these needs efficiently, the Office Manager must employ the most appropriate business methods, systems and equipment.In an efficient administrative structure, clerical operations are organized so that they add to the profitability of the business. However, in many countries the number of clerical staff has increased while the total number of workers employed in production has fallen.To ensure that office services run smoothly, there must be the means to check, sort, copy and file correspondence and other paperwork. Today there is a growing range of machine that can be used to do such jobs. The size and resources of a company will determine how mechanized or computerized its office systems are.The office must give maximum service at minimum cost. A balance must be kept between production, marketing, and administration. As a company develops and grows, the contribution of administration will vary in kind and in value.The most important objective in modem offices is the processing of data in order to provide a means of business control, but in many companies there are weaknesses in the ability to manage communications efficiently. For example, some data are often used only by individual managers, and different departments in the same company may use different data processing systems. In order to contribute to business efficiency, however data processing must be a centralized service. The system which is required is one that looks at the total needs of a business and therefore assists management in making appropriate decisions quickly.An office may receive information by telecommunications, by mail or by computer. An office worker must have skill in language and arithmetic to handle this and other business information properly. Almost all office jobs require at least a high school education. Many employers prefer people who have taken courses beyond the high school level. A person can get such advanced training at a community college, or business or vocational school.An office requires a staff of managers to plan and direct work. As a business grows, so does the amount of information that must be handled by its office workers. The managers coordinate the activities of these employees so that accurate records can be kept concerning correspondence, inventory, payroll, sales, and taxes.
