单选题In a perfectly free and open market economy, the type of employer—government or private—should have little or no impact on the earnings differentials between women and men. However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same. Differences in the degree of discrimination would result in earnings differentials associated with the type of employer. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater. Thus, one would expect that, if women are being discriminated against, government employment would have a positive effect on women's earnings as compared with their earnings from private employment. The results of a study by Fuchs support this assumption. Fuchs' results suggest that the earnings of women in an industry composed entirely of government employees would be 14.6 percent greater than the earnings of women in an industry composed exclusively of private employees, other things being equal. In addition, both Fuchs and Sanborn have suggested that the effect of discrimination by consumers on the earnings of self-employed women may be greater than the effect of either government or private employer discrimination on the earnings of women employees. To test this hypothesis, Brown selected a large sample of white male and female workers from the 1970 census and divided them into three categories: private employees, government employees, and self-employed. (Black workers were excluded from the sample to avoid picking up earnings differentials that were the result of racial disparities.) Brown's research design controlled for education, labor-force participation, mobility, motivation, and age in order to eliminate these factors as explanations of the study's results. Brown's results suggest that men and women are not treated the came by employers and consumers. For men, self-employment is the highest earnings category, with private employment next, and government lowest. For women, this order is reversed. One can infer from Brown's results that consumers discriminate against self-employed women. In addition, self-employed women may have more difficulty than men in getting good employees and may encounter discrimination from suppliers and from financial institutions. Brown's results are clearly consistent with Fuchs' argument that discrimination by consumers has a greater impact on the earnings of women than does discrimination by either government or private employers. Also, the fact the women do better working for government than for private employers implies that private employers are discriminating against women. The results do not prove that government does not discriminate against women. They do, however, demonstrate that if government is discriminating against women, its discriminating is not having as much effect on women's earnings as is discrimination in the private sector.

单选题The vegetative forms of most bacteria are killed by drying in air, although the different species exhibit pronounced differences in their resistance. The tubercle bacillus is one of the more resistant, and vibrio cholcra is one of the more sensitive to drying In general, the encapsulated organisms are more resistant than the non-encapsulated forms. Spores are quite resistant to drying; the spores of the anthrax bacillus, for example, will germinate alter remaining in a dry condition for years or more. The resistance of the pathogenic forms causing disease of the upper respiratory tract is of particular interest in connection with airborne infection, for the length of time that a droplet remains infective is a result, primarily, of the resistance of the particular microorganism to drying.

单选题 Technology is a two-edged sword. Rarely is this as clear as it is in the realm of health care. Technology allows doctors to test their patients for genetic defects--and then to turn around and spread the results throughout the world via the Internet. For someone in need of treatment, that's good news. But for someone in search of a job or an insurance policy ,it can be all bad. Last week a corollary (推论) was proposed to the patients' bill of rights now before Congress: a right to medical privacy. Beginning in 2002 ,under rules set to become law in February ,patients would be able to decide the conditions under which their personal medical data could leak. They would be able to examine their records and make corrections. They could learn who else had seen the information. Improper use of records by a caregiver or insurer could result in both civil and criminal penalties. The plan was said to be an unprecedented step toward putting Americans back in control of their own medical records. While the administration declared that the rules as an attempt to strike a balance between the needs of consumers and those of the health-care industry, neither doctors nor insurance companies were happy. The doctors said the rules could actually destroy privacy, pointing to a stipulation allowing managed-care plans to use personal information without consent if the purpose was "health-care operations". That, physicians said, was a loophole (漏洞) through which Health Maintenance organizations and other insurers could pry(窥探)into the doctor-patient relationship, in the name of assessing the quality of care. Meanwhile, the insurers protested that the roles would make them vulnerable to lawsuits. They were especially disturbed by a stipulation holding them liable for privacy breaches (违背)by "business partners" such as lawyers and accountants. Both groups agreed that privacy protections would drive up the cost of health care by at least an additional $ 3.8 billion, and maybe much more, over the next five years. They also complained about the increased level of federal scrutiny required by the new rules' enforcement rules. one aim of the rules is to reassure patients about confidentiality, thereby encouraging them to be open with their doctors. Today various cancers and other embarrassing diseases can go untreated because patients are afraid of embarrassment or of losing insurance coverage. The fear is real: an official noted that a January poll by Princeton Survey Research Associates found that one in six U. S. adults had at some time done something unusual to conceal medical information, such as paying cash for services.
