Why do some countries appear more popular than others in mass media? Although researchers have long sought to explain foreign countries’ prevalence in the media, to date they have exclusively focused on news, leaving other types of media content unexplored. In addition, focusing on media effects and media content, the literature on entertainment and politics has largely ignored the study of agenda-building processes. Thus, this study fills these gaps by exploring factors affecting the volume of references to foreign countries in both U.S. news and entertainment media. Analyzing more than 400 U.S. television shows, four news channels, and two newspapers spanning from 2000 to 2011, we reexamine past findings on salience of foreign countries in the news and apply these findings to a new field of research, entertainment media. We further suggest that the same factors shaping foreign countries’ prevalence in the news media are applicable to both news and entertainment and that in the context of foreign countries’ prevalence, the criteria for “newsworthiness” and “fictionworthiness” is similar.  相似文献

The increased familial and environmental stressors affecting Head Start families over the last two decades have precipitated an escalation of mental health difficulties among participant children (Yoshikawa & Knitzer, 1997). Using an ecological framework (Bronfenbrenner, 1979). this study explored externalizing behavior problems among a group of Head Start children in a suburban county. Children were assessed for externalizing behavior problems in the home and classroom. Additionally, parents participated in interviews about a variety of ecological factors related to children's behavior problems. Almost one-quarter of the children were identified by their parents as having externalizing behavioral problems in the borderline or clinical range. Twice as many girls as boys had borderline or clinical levels of behavioral problems. Child externalizing behavior was positively associated with child internalizing behavior, parent psychological symptomatology, child temperament, family environment, and exposure to community violence. Children with parent-identified externalizing behavior did have specific social problem-solving skills deficits. Additionally, they were observed to have high levels of specific inappropriate behavior, but did not exhibit high levels of teacher-rated behavior problems. The implications of these findings for Head Start program planning are discussed.  相似文献

In this study, we examine the impact and the interplay of general giftedness (G) and excellence in mathematics (EM) on high school students’ mathematical performance associated with translations from graphical to symbolic representations of functions, as reflected in cortical electrical activity (by means of ERP—event-related potentials—methodology). We report on findings of comparative data analysis based on 75 right-handed male high school students (16?–?18 years old) divided into four research groups designed by a combination of EM and G factors. Effects of EM factor appeared at the behavioral and electrophysiological levels. The fifth group of participants included 9 students with extraordinary mathematical abilities (S-MG: super mathematically gifted). We found that in EM participants, the G factor has no impact on the performance associated with translation between representations of the functions. The highest overall electrical activity is found in excelling in mathematics students who are not identified as generally gifted (NG-EM students). This increased electrical activity can be an indicator of increased cognitive load in this group of students. We identified accumulative and unique characteristics of S-MG at the behavioral and electrophysiological levels. We explain the findings by the nature of the tasks used in the study. We argue that a combination of the ERP techniques along with more traditional educational research methods enables obtaining reliable measures on the mental processing involved in learning mathematics and mathematical problem solving.  相似文献

This paper offers personal reflections on the fashioning of the history of science in Europe. It presents the history of science as a discipline emerging in the twentieth century from an intellectual and political context of great complexity, and concludes with a plea for tolerance and pluralism in historiographical methods and approaches.Robert Fox held the chair of the history of science at Oxford University between 1988 and 2006. He has been active in a number of international organizations, including the International Union of the History and Philosophy of Science, of which he is a past president, and the European Society for the History of Science, whose founding president he became in 2004.  相似文献

The aims of this study were to present a method for developing a path analytic network model using data acquired from positron emission tomography. Regions of interest within the human brain were identified through quantitative activation likelihood estimation meta-analysis. Using this information, a “true” or population path model was then developed using Bayesian structural equation modeling. To evaluate the impact of sample size on parameter estimation bias, proportion of parameter replication coverage, and statistical power, a 2 group (clinical/control) × 6 (sample size: N = 10, N = 15, N = 20, N = 25, N = 50, N = 100) Markov chain Monte Carlo study was conducted. Results indicate that using a sample size of less than N = 15 per group will produce parameter estimates exhibiting bias greater than 5% and statistical power below .80.  相似文献

Parent coaching strategies during shared book reading were analysed according to the principles of scaffolding in a sample of 46 parent-child dyads during the latter half of grade one. The ways that parents responded to each of a child's oral reading errors or miscues were coded into levels of assistance that reflected increasing support at each successive level. In addition children's attempts at rereading miscued words were coded as successful or not. Parents often provided a string of feedback clues and analyses revealed that the level of support parents provided shifted up or increased when their child was unsuccessful in rereading a word after feedback. With increasing level of parental support children's success in rereading misread words increased. Moreover, children with weaker word recognition skill were offered feedback at higher levels of support by their parents. These results demonstrate how parents and children co-construct the feedback that parents provide when listening to their children read and the sensitivity on the part of parents to children's reading performance.  相似文献
