In this essay I will argue, as does Bernard Williams, that lying and misleading are both commonly wrong because they involve an aim to breach a trust. I will also argue, contrary to Williams, that lying and misleading threaten trust differently, and that when they are wrong, they are wrong differently. Indeed, lying may be wrong when misleading is not.  相似文献

This paper has two objectives. The first is to formulate a critique of present-day cognitive linguistics (CL) concerning the inner workings of the cognitive system during language use, and the second is to put forward an alternative account that is inspired by the phenomenology of Merleau-Ponty. Due to its third-person methodology, CL views language use essentially as a problem-solving activity, as coping with two subproblems: the problem of minimum and maximum, which consists in selecting the appropriate expression out of an unlimited multitude of possibilities, and the problem of the underdetermination of signification. This approach presupposes a notion of an isolated subject and a representationalist view of perception. We defend an alternative view of man's relation to the world in which intersubjectivity is constitutive of embodied subjectivity and which exchanges the representationalist view of perception for a direct nonrepresentationalism. We describe the ensuing view of linguistic action as intra- and interpersonal “all-at-onceness.” This approach dismisses the two subproblems CL implicitly identifies as constitutive of language use. The first is countered by rethinking what it means to be a situated speaking subject and results in the concept of “style.” The second is tackled by opposing the concept of “overdetermination” to CL's notion of underdetermination.  相似文献

Issues of responsibility in the world of nanotechnology are becoming explicit with the emergence of a discourse on ‘responsible development’ of nanoscience and nanotechnologies. Much of this discourse centres on the ambivalences of nanotechnology and of promising technology in general. Actors must find means of dealing with these ambivalences. Actors’ actions and responses to ambivalence are shaped by their position and context, along with strategic games they are involved in, together with other actors. A number of interviews were conducted with industrial actors with the aim of uncovering their ethical stances towards responsible development of nanotechnology. The data shows that standard repertoires of justification of nanotechnological development were used. Thus, the industrial actors fell back on their position and associated responsibilities. Such responses reinforce a division of moral labour in which industrial actors and scientists can focus on the progress of science and technology, while other actors, such as NGOs, are expected to take care of broader considerations, such as ethical and social issues.  相似文献

Three decades after their publication, Bloom and Fischler’s (1980) sentence completion norms continue to demonstrate widespread utility. The aim of the present study was to extend this contribution by expanding the existing database of high-constraint, high cloze probability sentences. Using the criteria established by Bloom and Fischler, we constructed 398 new sentences and presented these along with 100 sentences from their original list to be normed using a sample of 400 participants. Of the 498 sentences presented, 400 met criteria for high cloze probability—that is, .67 or higher probability of being completed by a specific single word. Of these, 321 sentences were from the new set and an additional 79 were from Bloom and Fischler’s set. A high degree of correspondence was observed between responses obtained by Bloom and Fischler for their high-constraint set. A second experiment utilized an N400 event-related potential paradigm to provide further validation of the contextual constraint for the newly generated set. As expected, N400 amplitude was greater for sentences that violated contextual expectancy by ending in a word other than the newly established completion norm. Sentence completion norms are frequently used in cognitive research, and this larger database of high cloze probability sentences is expected to be of benefit to the research community for many years to come. The full set of stimuli and sentence completion norms from this study may be downloaded from http://brm.psychonomic-journals.org/ content/supplemental.  相似文献

The present study examined the effects of illness representation, perceived quality of information provided by the health-care professional, and perceived social support on the depressive symptoms of the caregivers of children with leukemia. The sample was composed of 71 caregivers of children with leukemia living in Turkey. The obtained data were analyzed by path analysis. The results show that caregivers of children with leukemia experience higher levels of depressive symptoms when they have negative illness representation and lower levels of depressive symptoms when they perceive higher levels of social support. Moreover, they perceive higher social support when they perceive high quality of information provided by health-care professionals. It can be suggested that intervention programs which aim to increase caregivers’ social support and change their illness representation in a positive way would be helpful for the caregivers showing depressive symptoms.  相似文献

In the past two decades a virtual Ummah has evolved in cyberspace. While some of these websites are targeted specifically at Muslims, others attempt to provide outreach on Islam or counter Islamophobic bias. As noted by Jon Anderson, in his pioneering work on Islam in cyberspace, Muslims were among the first engineering students to create websites at the dawn of the Internet, before mainstream Islamic organizations posted official websites. There is a wealth of material by Muslims in English and Western languages, some of it archived for research. This article explores the methodological problems posed in studying the range of Islam-content blogs, from private individuals to religious scholars, as well as Muslim websites that feature comments from readers. The focus of the paper is an analysis of blogs about Islam or by Muslims that either act as watchdogs on the media or try to provide alternative views to the mainstream media of competing Muslim groups. Researching these blogs as a form of e-ethnography calls for a rethinking and refining of anthropological methodology as e-ethnography.  相似文献

The current study examined how work support resources and working from home influenced forms of work-family conflict (WFC) in employees at a large corporation. Scales measuring employee’s general WFC, time-based WFC, and strain-based WFC were used to evaluate the extent to which employees experienced work-induced conflict at home. Two forms of working at home were assessed, days worked at home and extra hours worked at home, and five variables measured the extent of one’s support resources: work social support, organizational support, individual consideration from one’s manager, idealized influence from one’s manager and contingent reward from one’s manager. We predicted that days worked at home would be negatively related to the three forms of WFC, while the extra hours worked at home would be positively related. Moreover, we hypothesized that the five support variables would moderate the relationship between extra hours worked at home and the types of WFC. The data supported some of the predictions, and the implications of these findings are discussed.  相似文献

The transition to parenthood is a substantial challenge for many couples, and the extent to which the partners can support each other and their relationship is strongly related to the sensitivity and responsiveness of their parenting of their infant. This paper critically analyses the links between the couple relationship and parenting of infants and reviews the research evaluating couple psychoeducation (CP) to assist couples’ parenting of their infant. It is concluded that CP has considerable potential to enhance couples’ adaptation to parenthood and enhance the sensitivity and responsiveness of parenting of new infants.  相似文献

In this commentary, I argue that although emotion regulation and its role in psychopathology has been the focus of considerable psychological research with both children and adults, fundamental questions remain about how these phenomena are linked. I pose four challenges to the study of emotion regulation and psychopathology that have yet to be fully met, either empirically or conceptually. I note that a multi-level developmental approach that places emotion regulation within the context of both the larger self-regulatory system and the social relationships within which regulation occurs may be useful in understanding the emergence and maintenance of early behavioral patterns that evolve into disorders of psychological functioning.  相似文献

Considerable evidence indicates that African American students achieve less academically than European American students. Yet, African American students hold more positive self-views than their European American counterparts. Previous studies that address these seemingly paradoxical findings focus on students in a relatively narrow age range and/or convenience samples. Therefore, the current study examines two common explanations for these seemingly paradoxical findings, among a large and diverse sample of African American and European American students (N = 1, 493) from elementary to post-secondary school and across the socioeconomic spectrum. Results indicate that among a diverse group of students and conceptualized in two different ways, African American students do not devalue academics. However, African American students are more likely than European American students to discount academic feedback.  相似文献
