The cumulative data from the National Opinion Research Center General Social Survey for 1972–1978 are used to test a model of allocation of time to work in families in which both spouses are employed. Using number of hours worked during the previous week as a dependent variable, we find that for white respondents, women work fewer hours than men; fathers of preteenaged children work more hours than other men, while mothers of preteens work fewer hours than other women; both men and women work more hours when they have higher prestige occupations; and both work more hours if their status (measured by education and prestige) is equal to or higher than their spouses'. Number of hours reported for spouse in the previous week is positively related to number of hours reported by respondent. The model suggests that within two-income families equality of occupational status is associated with equality of occupational involvement, while inequality of occupational status is associated with lower occupational involvement of the spouse with lower status. 相似文献

This study investigated the degree and congruence of students' estimated and actual information about gender traditional and nontraditional occupations. Twenty-nine female and 29 male college students completed an instrument on which they rated how much they thought they knew about 18 male-dominant and 18 female-dominant occupations. They also completed an instrument measuring their actual knowledge of these and an additional wide variety of occupations. Results showed that subjects of each sex perceived themselves as less informed about nontraditional occupations. This result was much more pronounced for women than men. Each sex also tended to underestimate their actual knowledge of nontraditional occupations. Men and women did not differ in their actual knowledge, which was fairly limited for both sexes. 相似文献

A field experiment conducted in high schools throughout the country was aimed at increasing the number of high school students who donate blood. Special interventions that emphasized psychological or educational approaches to heightening motivation to donate, as well as a combined intervention, were compared with the usual approach taken at blood drives. Psychological interventions in which social learning principles (modeling, perceptions of social norms) played important roles either alone or in combination with an educational (informational) approach were more successful in stimulating blood donations than either an educational approach alone or the approaches traditionally followed by the participating local blood centers. The results demonstrated that use of social learning principles in designing interventions to strengthen socially relevant altruistic behavior could be valuable both practically and theoretically. 相似文献

This study examined the relationships among five measures that assess various cognitive components of the child's acquisition of gender. At around 2 years of age, children were given a task assessing their ability to accurately label as a boy or a girl some head-and-shoulders pictures of boys and girls. At 4 years of age, these children were given tasks measuring (1) the degree to which they found gender a salient parameter of categorization, (2) the amount of gender-related knowledge they could display (SERLI-SRD), (3) the degree to which their preferences were gender-typed (SERLI-SRP) and (4) the accuracy of their memory for gender-typed information. There was no consistent pattern of relationship among the children's scores on these five tools for measuring gender acquisition. Our findings suggest that gender is a multidimensional construct in children's development, and thus these results challenge the undimensional manner in which gender is repeatedly addressed in developmental theory and research.This research was funded in part by a federal biomedical research grant (No. 2507RR07080) awarded to the first author from the Department of Psychology at the University of Oregon, and by Grant No. RO1HD175751 from the National Institute of Child Development awarded to the third author.We wish to thank Margo Lane, Rachel Robertson, Jacqui Oucalt, Laura Baker, Dale Roberts, and the teachers, parents, and assistants of the Child Research Laboratory at the University of Oregon in Eugene, Oregon, for their invaluable contribution to this research. 相似文献

This study examined the effects of personal religious orientation, religious denomination, and gender on attitudes toward women and their work roles using a sample of 263 single undergraduate university students. Subjects with a high intrinsic religious orientation put significantly more emphasis on family than career in their anticipated general lifestyle relative to those with a low intrinsic religious orientation. Subjects with a high intrinsic religious orientation were also more likely to anticipate the female spouse spending less time in a profession during the children's early years. Males showed more traditional attitudes toward women than females, but there were no gender effects on measures of preferred general lifestyle, preferred child-care distribution, or preferred career involvement for the wife. Subjects belonging to mainline and conservative denomination did not differ significantly in their attitudes toward women or their work roles. 相似文献

Erich H. Loewy proposes to elevate the moral obligation to prevent and relieve suffering to the level of a prima facie moral duty by delineating which beings are of primary moral worth and which are of secondary moral worth. Sentient beings have a capacity to suffer and are therefore of primary moral worth. Beings that are insentient cannot suffer; therefore such beings are only of secondary moral worth. Objects of secondary moral worth include patients in a persistent vegetative state (PVS) and brain-dead patients. This proposal, he says, would solve a number of problems in clinical bioethics. First, it would help to clarify our moral duties at the bedside. And secondly, by creating a hierarchy of moral values, it helps to differentiate which patients are owed our primary allegiance and resources. Despite his extensive and painstaking proof, I believe several questions remain about the use of the "capacity of sentient beings to suffer" as a basis for a universal grounding in ethics. 相似文献

Visuoperceptual deficits are common sequelae of damage to either hemisphere of the brain, but are typically more pronounced following injuries involving the right cerebral hemisphere. Common visuoperceptual disorders include visual field cuts, hemi-inattention and hemi-spatial neglect, hemi-perceptual deficits, and gaze and visual pursuit disturbances. A number of behavioral interventions have been developed to teach patients to compensate for acquired visual deficits. Studies addressing assessment and treatment issues in this area are reviewed, and future directions for research are outlined. 相似文献

Ashcraft (1978b) found that people tend to know more properties of instances they rate as typical of a category than of instances they rate as atypical. This suggests that variations in typicality result from variations in familiarity. Three experiments are presented that challenge or qualify this suggestion. Experiment 1 showed that subjects sometimes produce more properties for items they rate as low in typicality. Experiment 2 showed that in a large, random sample of items, there was a tendency to produce fewer properties for atypical items, but Experiment 3 indicated that part of the reason for this result was a response bias to assign low typicality ratings to unfamiliar words, rather than a reflection of low perceived typicality of the referents themselves. These results suggest that variations in typicality can exist independent of variations in familiarity, although familiarity may also play a role. 相似文献

To test the reliability of children's reporting as compared with that of their mothers, a highly structured psychiatric diagnostic interview was used with 307 subjects, ages 6 through 16. Another interviewer gave each mother a similar interview about the child. Responses of each mother-child pair to 168 questions were compared using the kappa statistic. Highest agreement was found on questions concerning symptoms that are concrete, observable, severe, and unambiguous. Mothers tended to report significantly more behavioral symptoms, and children more subjective symptoms. Reasons for low kappas and asymmetrical reporting of symptoms are discussed. 相似文献
