The feminist ethic of care has often been criticized for its inability to address four problems--the problem of exploitation as it threatens care givers, the problem of sustaining care-giver integrity, the dangers of conceiving the mother-child dyad normatively as a paradigm for human relationships, and the problem of security social justice on a broad scale among relative strangers. We argue that there are resources within the ethic of care for addressing each of these problems, and we sketch strategies for developing the ethic more fully. 相似文献

In a replication of two investigations reported by Looft (1971a, 1971b), 40 second- and sixth-grade male and female students were interviewed concerning their desired and expected vocational aspirations. In contrast to Looft's findings, no significant sex differences were found for either grade level in (a) the number of different (nonoverlapping) vocations nominated or (b) the number of subjects changing initial vocational role choices. When the issue of traditionality of vocational choice (i.e., vocations socially identified with the sex of the subject) was examined, it was found that half of the sixth-grade females interviewed nominated nontraditional vocations (e.g., basketball player, police officer). It was observed further that males in both the second- and sixth-grade samples overwhelmingly nominated traditional vocations. Contrary to Looft's interpretation, the findings suggest that although goals associated with the women's liberation movement (e.g., changes in sex-role expectations) are not demonstrated clearly in the vocational aspirations or expectations of young children, they may be reflected in the aspirations of adolescent females. 相似文献

Short-term memory for 16 monochromatic hues from 425 to 640 nm was measured after six delays from .1 to 24.3 sec by means of an iterative, momentary stimulus-matching technique. Small shifts were revealed in the remembered hue produced by certain wavelengths at some delays. These shifts did not follow trends consistent with a storage dependent on sensory pathway characteristics, perceptually unique hues, or semantic encoding but may reflect entropic effects in a storage that is remarkably unbiased. By indicating the discriminability of hues in memory, standard deviations of the delayed matches reveal other characteristics of what is stored: Their smooth, exponential growth questions the existence of "levels" and permits estimating the half-life of hue memory; their continued resemblance to the discrimination function for simultaneously perceived hues suggests that the stored activity; closely resembled the sensory response of color. The results also indicate how successive comparisons may be corrected in applied color work. 相似文献
