Case study A man, 26 years of age, presented to a hospital emergency department complaining of a sudden onset of a sore throat 6 hours previously while consuming a carbonated drink at work. The pain commenced about lunchtime, after he had been mixing concrete powder, and since then had been intermittent and was becoming more severe. 相似文献

The authors' disquietudes are related to the structure for supporting women to breastfeed within their family environment. It is a qualitative study aiming at understanding the significance of breastfeeding among mothers and primiparous daughters, as well as identifying how the mother perceive herself as a means of support for her primiparous daughter and vice versa. The historic social construction of women for maternity has been used as a theoretical referential. The sample was made up of 10 women--five primiparous daughters and their mothers. The participation of the mother in her daughter's maternity was "to be along with her", sharing knowledge and life experiences. 相似文献

The arguments advanced by birth control advocates for population limitation policies are identified and characterized as a barrier to solving fundamental economic and social problems in both developing and advanced countries, and are characterized as a component of imperialist foreign policy and investment interests. It is argued that the materialist basis for family size is generally determined by cultural factors more than the sole factor of the availability or nonavailability of contraceptives. However, it is agreed among most proponents of population control that traditional ideas on family size must be modified by enlisting social science technology for attitude correction and behavior modification. Some of these schemes are coercive and blame the people's large families for society's ills-thereby serving to divert blame for entrenched political elites and leaving the real problems unsolved. Thus, population control programs treat the symptoms of excessive growth rate rather than the disease of a social order permitting little hope for a better future. A workable alternative policy would be a development program marked by labor-intensive industra lization, nonelite education systems, and the erosion of traditional sex ist roles, thereby undermining the basis for large families. Birth control would also be a desirable element in such a program. 相似文献

Wire screens are commonly used to estimate "unattached" Rn daughter fractions in ambient and mine atmospheres. However, it is now recognized that the "unattached" fraction is in reality an ultrafine cluster mode in the 0.5-3 nm size range and that the collection efficiency versus particle diameter characteristics of wire screens do not permit a distinct separation of the "unattached" and "attached" fractions. Wire screen penetration theory and a semi-empirically corrected diffusion coefficient equation are used to characterize "unattached" fraction measurements as a function of experimental parameters. Collection efficiency curves are estimated for previously published wire screen "unattached" fraction measurements, and improvements in wire screen methods for such measurements are discussed. 相似文献

Scarcities of qualified personnel are becoming a common phenomenon in The Netherlands. At the same time, increasing wages to secure an adequate workforce is not always possible or sufficiently effective, and other ways of retaining and recruiting personnel have to be found. Investigates the importance of various job characteristics for retaining and recruiting employees and presents the results from a survey among employees of a Dutch hospital experiencing a tight labour market. Job characteristics other than wages, such as labour relations and work content, were found to play a major role in individuals' choices to resign or stay. Discusses consequences for employment strategies in other organizations. 相似文献

Today it is estimated that over 100 million women worldwide have taken the oral contraceptive pill since 1956, when the first clinical trials were undertaken. Since its introduction on to the American market in 1960 and the British one in 1961, the pill has become one of the most popular contraceptives in both countries. Unlike other forms of drugs, which have primarily been formulated to prevent or cure illness, the oral contraceptive pill was designed to be given to healthy women over long periods of time, making the necessity for regulation and medical monitoring that much more pertinent. Focusing on the USA and Britain, this paper concentrates on the different ways in which each country has monitored and secured the safety of the pill between 1960 and 1970. While the British government decided to phase-out high dose oestrogen contraceptive pills associated with thrombotic disease in 1969, such pills continued to be available in the USA through to the 1980s, with measures instead being directed towards supplying better information to patients about the possible side-effects of the pill. The paper explores the reasons for this difference in policy, showing how it was shaped by the particular research orientation of each country as well as the specific legal, medical, social and political traditions within Britain and the USA. 相似文献
