It is widely accepted that regular physical exercise helps diabetic patients control blood glucose, reduce cardiovascular risk factors, and prevent other related complications. In spite of the undoubted benefits of regular physical exercise, diabetic patients with chronic complications should be aware of potential hazards of practicing exercise. To avoid some harmful consequences of acute exercise, it is necessary to adopt a vigilant attitude with these risk patients and to carefully adjust type and intensity of exercise to the individual situation. This article intends to summarize and analyze the current literature concerning the preventive and therapeutic effects of regular exercise in diabetic patients, pointing out its physiological influence on blood glucose regulation, and to analyze the potential risks of acute physical exercise and the precautions given to patients with a variety of complications. 相似文献

Attitudes towards ‘wallbanking’ (making use of banking services through an Automated Teller Machine (ATM)) and self-reported frequency of wallbanking have been related to attitudes towards innovations and towards computers. The investigation also included the perception of advantages as well as disadvantages of wallbanking, factors that determine one's choice of a bank, man-machine problems related to the use of an ATM, and demographic factors. Using a sample of 201 respondents in the age range of 25 to 40 years, structural equation modeling revealed that wallbanking attitudes have a major influence on the frequency of using ATMs. The innovativeness attitude ‘New is wasteful’ also showed a clear negative link with the frequency of wallbanking. On the other hand, the relationship between computer attitudes and the frequency of using ATMs had to be rejected. Income and education proved to have an indirect link with the frequency of wallbanking, which refines other research findings. These results may reflect specific financial management characteristics of the age group under investigation. 相似文献

Obtaining information on current child injury trends and their associated issues is an important factor in developing products that meet or surpass acceptable toy safety boundaries. Understanding these boundaries helps determine safe product design characteristics that reduce the risk of product-related injury. Inchcape Testing Services developed a Small Parts Aspiration, Ingestion, and Choking Hazards Research Project, independent of an ongoing consumer Product Safety Commission (CPSC) project. The project's purpose was to determine, independent of CPSC, whether a more stringent small parts regulatory standard was necessary and, if so, to ensure that the standard was determined objectively. This article reports on the project's findings relating to critical characteristics (size, shape, and consistency) relative to the victim's age, of objects responsible for child choking injuries and fatalities. 相似文献

美国在中国的经济扩展,迟于欧洲各国及日本。一次大战后,美国在中国从政治、经济、文化等方面加强活动,以增强在中国的竞争力。中国留美学生和美国“世界主义者”对这些活动也起了促进作用。美国这些努力为30年代中美关系的发展打下了基础。 相似文献

Consumers need to exert effort to use the incentives provided in a promotion campaign. This effort is critical in the consumers’ decision process and for the success of the campaign. We develop a model of consumer redemption effort that is general in nature and is applicable to coupons, rebates, and other price‐discrimination devices. We find that the impact of redemption effort is quite intricate on a firm’s profit and consumers’ surplus. We find that there are cases where a firm would like to operate in a low redemption cost environment while consumers would be better off with higher costs. We identify cases where price can remain the same with or without the promotion. In these cases, it is possible that the surplus for each individual consumer is higher when a firm price discriminates and improves its profit. Our results indicate that a firm would rather have variation in consumer redemption costs than to have variation in consumer valuations. However, in a market with low valuation variability, consumer redemption cost variability is essential for an efficient promotion campaign. Therefore, the markets that naturally have a lot of variability in consumer valuations should be the ones targeted for online promotion programs that reduce consumer effort levels, not the markets with low variability. 相似文献
