Framing is the least well-developed central concept of prospect theory. Framing is both fundamental to prospect theory and remarkably underdeveloped in the prospect theory literature. This paper focuses on the many subtypes and variations of framing: thematic vs. evaluative; successful vs. failed; productive vs. counterproductive; purposeful, structural and interactive framing; counterframing; loss frames vs. gain frames; revolving framing vs. sequential framing; framing by a third party; and framing vs. priming. The bulk of the paper provides an analysis of framing and framing effects in foreign policy settings with an emphasis on U.S. foreign policy. We highlight framing effects during the Cold War, the Persian Gulf War, the current ``war on terrorism', and other IR/foreign policy settings. Our examination highlights the extent to which presidents and other significant world leaders use framing to shape policy debates and national security choices. 相似文献

Over the past couple of decades, research has established that infants are sensitive to the predominant stress pattern of their native language. However, the degree to which the stress pattern shapes infants' language development has yet to be fully determined. Whether stress is merely a cue to help organize the patterns of speech or whether it is an important part of the representation of speech sound sequences has still to be explored. Building on research in the areas of infant speech perception and segmentation, we asked how several months of exposure to the target language shapes infants' speech processing biases with respect to lexical stress. We hypothesize that infants represent stressed and unstressed syllables differently, and employed analyses of child-directed speech to show how this change to the representational landscape results in better distribution-based word segmentation as well as an advantage for stress-initial syllable sequences. A series of experiments then tested 9- and 7-month-old infants on their ability to use lexical stress without any other cues present to parse sequences from an artificial language. We found that infants adopted a stress-initial syllable strategy and that they appear to encode stress information as part of their proto-lexical representations. Together, the results of these studies suggest that stress information in the ambient language not only shapes how statistics are calculated over the speech input, but that it is also encoded in the representations of parsed speech sequences. 相似文献

This paper introduces the notion of frequent frames, distributional patterns based on co-occurrence patterns of words in sentences, then investigates the usefulness of this information in grammatical categorization. A frame is defined as two jointly occurring words with one word intervening. Qualitative and quantitative results from distributional analyses of six different corpora of child directed speech are presented in two experiments. In the analyses, words that were surrounded by the same frequent frame were categorized together. The results show that frequent frames yield very accurate categories. Furthermore, evidence from behavioral studies suggests that infants and adults are sensitive to frame-like units, and that adults use them to categorize words. This evidence, along with the success of frames in categorizing words, provides support for frames as a basis for the acquisition of grammatical categories. 相似文献

This study examined men's gender role factors (i.e., gender role orientation and gender role conflict) as they contribute to the formation of either traditional, participant, or rolesharing family roles in men. Responses from 71 married, mostly Caucasian, dual-career family men on measures of gender role orientation, gender role conflict, and measures of participation in child care and management of the household were analyzed. Results indicated that (a) rolesharing husbands were more likely to view their wives' interests as equal to their own as compared to participant and traditional husbands; (b) rolesharing husbands had less traditional attitudes about husbands'/fathers' authority than traditional husbands; and (c) traditional husbands reported greater pressure to be successful, powerful, and competitive compared to rolesharing and participant husbands. 相似文献

Medical language frequently contains linguistic forms that serve to create a social distance between physicians and patients. This distance develops not only out of poor communication with the patient, but also, and more importantly, arises as the language that a physician uses comes to modulate his or her experience of the patient. It is suggested that some of the problem lies in the very nature of language itself, and that further fault can be found in the particular structures of Western language. Unfortunately, however, medical language has adopted special forms and metaphors which further serve to create distance. 相似文献

This paper questions the ethicality of commercial relationships between universities and external donors. By examining cases
such as technology transfer and the outside funding of research interests, we identify possible conflicts of interest between
the external provider of financial support and academic institutions. The reality today is that university administrators,
who have significant decision-making powers, proactively seek large corporate sources of funding that may compromise academic
values including academic freedom and the ability to make institutional decisions without the influence of commercial interests.
For example, Coca-Cola and Pepsi-Cola have provided extensive funding to universities in return for exclusivity rights to
market their product on campuses even though such products may not be healthy alternatives to other soft drinks. Pharmaceutical
and biotechnology companies may have opposing interests to faculty and universities if the results of research do not meet
the expectations of the sponsors. Curricula issues may be slanted to promote the interests of a corporation or other provider
of outside funding. Corporate partnerships between universities and companies such as Nike raise ethical questions when students
or other members of the campus community object to the acceptance of financial support from a company that allegedly practices
anti-social labor practices in developing countries. On the other hand, corporate funding can be used to supplement diminishing
financial resources available to academic institutions, especially for public universities. One benefit of external funding
is that it supports pharmaceutical and technology-oriented research and development into new products and processes that have
the potential to serve the public good. One cost of such funding arrangements is that the acceptance of financial support
from commercial interests solely to market their products on campus restricts the choices available to students that should
exist in a free market economy such as in the U.S. The ethicality of the relationship between universities and commercial
interests is a matter of concern because of the potential influence of providers of external funds to universities that can
compromise academic freedom and objective decision making. 相似文献
