The American press began to take notice of the Danish cartoons after they began to circulate outside of Europe. The press primarily framed the events as a single problem of global interaction: an issue of ‘freedom of speech’ opposed to ‘religious sensitivity.’ Much of the coverage permitted, within limits, a plurality of voices. Drawing on a case study of stories about the ‘cartoon controversy’ in the Boston Globe, I argue that U.S. journalism is organized by a logic of objectivity that seeks to produce a ‘perspectiveless perspective on all perspectives’ (Bourdieu, On television. New York: The New Press, 1998), showing voices on ‘both sides,’ simultaneously masked and contributed to the press’s reifying a series of events into a single global ‘event,’ one that reflected a clash of Western and Islamic values.

Although it has been suggested that the delayed realization of intended actions should benefit from appropriate intention planning, empirical evidence on this issue is scarce. In three experiments, we examined whether and which planning aids provided in the intention formation phase affect delayed intention realization in young and old adults. One finding was that intention planning directly affected delayed intention realization: instructing participants to include the cue for appropriate intention initiation in their plans benefited delayed performance. Another finding was that older adults' performance was improved when they were guided in structuring their plan in combination with guidance in implementing this plan after a delay. In sum, the results point to the importance of plan-related factors for understanding the delayed realization of intended actions.  相似文献

This study investigated associations between maternal prenatal smoking and physical aggression (PA), hyperactivity-impulsivity (HI) and co-occurring PA and HI between ages 17 and 42 months in a population sample of children born in Québec (Canada) in 1997/1998 (N=1745). Trajectory model estimation showed three distinct developmental patterns for PA and four for HI. Multinomial regression analyses showed that prenatal smoking significantly predicted children’s likelihood to follow different PA trajectories beyond the effects of other perinatal factors, parental psychopathology, family functioning and parenting, and socio-economic factors. However, prenatal smoking was not a significant predictor of HI in a model with the same control variables. Further multinomial regression analyses showed that, together with gender, presence of siblings and maternal hostile reactive parenting, prenatal smoking independently predicted co-occurring high PA and high HI compared to low levels of both behaviors, to high PA alone, and to high HI alone. These results show that maternal prenatal smoking predicts multiple behavior regulation problems in early childhood.  相似文献

This study evaluated the validity and classification utility of the Conners' Continuous Performance Test (CCPT) in the assessment of inattentive and hyperactive-impulsive behaviors in children. Significant, positive correlations between the CCPT parameters and behavioral ratings of ADHD behaviors were hypothesized. In addition, it was hypothesized that the CCPT parameters would perform better than a random test (chance) and show fair to moderate utility of classification across the different indices. Participants were 104 children between 6 and 12 years of age who were referred for evaluation of attention problems. The first hypothesis was not supported. There were no significant, positive correlations between the CCPT parameters and parent and teacher ratings of inattentive and hyperactive-impulsive behaviors. The second hypothesis was only partially supported. The CCPT Overall Index and the Omission Errors (84th percentile cutoff) performed better than a random test; however, the utility of the CCPT Overall Index only ranged from poor to slight. Receiver operating characteristic analyses showed the accuracy of the CCPT to be low. The implications and limitations of this study and future research directions are discussed.  相似文献

A considerable body of empirical and theoretical research suggests that morphological structure governs the representation of words in memory and that many words are decomposed into morphological components in processing. The authors investigated an alternative approach in which morphology arises from the interaction of semantic and phonological codes. A series of cross-modal lexical decision experiments shows that the magnitude of priming reflects the degree of semantic and phonological overlap between words. Crucially, moderately similar items produce intermediate facilitation (e.g., lately-late). This pattern is observed for word pairs exhibiting different types of morphological relationships, including suffixed-stem (e.g., teacher-teach), suffixed-suffixed (e.g., saintly-sainthood), and prefixed-stem pairs (preheat-heat). The results can be understood in terms of connectionist models that use distributed representations rather than discrete morphemes.  相似文献

Three studies consider a basis for intergroup helping. Specifically, they show that group members may help others to disconfirm a stereotype of their own group as mean. Study 1 shows that Scots believe they are seen as mean by the English, resent this stereotype, are motivated to refute it, and believe out-group helping is a particularly effective way of doing so. Study 2 shows that increasing the salience of the English stereotype of the Scottish as mean leads Scots to accentuate the extent to which Scots are depicted as generous. Study 3 shows that increasing the salience of the stereotype of the Scots as mean results in an increase in the help volunteered to out-group members. These results highlight how strategic concerns may result in out-group helping. In turn, they underscore the point that helping others may be a means to advance a group's interest.  相似文献

A key area of difficulty for those engaged in pastoral counselling often concerns the adequate integration of pastoral, psychological and spiritual concepts and resources. The roots of this tension can be identified within modernity between what can be known through objective observation and reason over what is known through subjective experience. Pastoral counselling, in general, represents an attempt to hold together both scientific and subjective accounts of human existence. Existing forms of Christian pastoral counselling will benefit, however, through a deeper use of spiritual resources drawing both on transpersonal psychology and the tradition of Christian mysticism.  相似文献

Although females comprise 51% of the population, they are represented in less than that amount in children's literature. Psychologists and leaders of liberation groups affirm that gender stereotyping in children's books has detrimental effects on children's perception of women's roles. Therefore, illustrated children's books that view women positively can be used to eliminate these stereotypes. Eighty-three Notable Books for Children from 1995 to 1999 were analyzed for gender of main character, illustrations, and title. This research updated LaDow's content analysis method and revealed that contrary to earlier studies, steps toward equity have advanced based on the increase in females represented as the main character (S. LaDow, 1979). Although female representation has greatly improved since the 70s, gender stereotypes are still prevalent in children's literature.  相似文献

We report on our experiences in a participatory design project to develop ICTs in a hospital ward working with deliberate self-harm patients. This project involves the creation and constant re-creation of socio-technical ensembles that satisfy the various, changing and often contradictory and conflicting needs in this context. Such systems are shaped in locally meaningful ways but nevertheless reach beyond their immediate context to gain wider importance and to be integrated with the larger environment. currently working on a participatory design project developing IT systems for psychiatrists working in a toxicology ward of a large general hospital. His research focuses on the local co-production of technologies which he currently explores in a production management context. His research interests lie in the field of human factors and interactive systems design, particularly approaches to IT systems design and development, the relationships between work and technology, and inter-disciplinary approaches to the design of dependable computing systems. carrying out a number of ethnomethodologically informed studies in a variety of applications. He holds a Ph.D. in ethnomethodology from the University of Manchester and is currently involved in research on computer-aided prompting systems for radiological work. He has interests in ethnomethodology, CSCW, SSK and the philosophy of social sciences. where he convenes an interdisciplinary research programme on ‘the social shaping of technology’.  相似文献
