喷墨drupa——还没有到来

在最近的drupa展上．主要技术讨论都在关注超高速喷墨数码印刷机．以及它们对现有的静电复印技术类的数码印刷机和目前胶印所占地位所产生的影响。喷墨打印机应用在桌面打印,图形、标牌领域已经有一段很长的时间,但是,本届drupa还是第一次让我们看到很多不同的供应商提供高速喷墨连续纸的印刷机。那么．这会产生怎样的影响呢？     

An idealized self or the real me? Predicting attraction to online dating profiles using selective self-presentation and warranting

Online daters construct their profiles to attract potential partners and viewers’ assessments are based on the content of dating profiles. However, little is known about the mechanisms or nature of the associations that connect variations in profile content to outcomes. This study examined the presence of selective self-presentation (SSP) and warranting content as predictors of viewers’ impressions and intentions to act on dating profiles. A national sample of online daters (N?=?316) provided their impressions and intended outcomes after viewing manipulated dating profiles. Results indicate that high levels of SSP decrease intentions to act on a dating profile because users find these profiles to be less socially attractive, whereas profiles with high warranting value increase positive outcomes by eliciting trust.     

Examining the World’s Game in the United States: Impact of Nationalized Qualities on Fan Identification and Consumption of the 2014 FIFA World Cup

To explore the role of media consumption as it relates to impressions of one’s nation, data were collected using a nationally generalizable sample of 979 American citizens over 6 different collection points before, during, and after the 2014 FIFA World Cup. Results showed a relationship between 4 nationalized qualities (patriotism, nationalism, smugness, and internationalism) and amount of World Cup media consumption. However, these reported qualities fluctuated very little over time, indicating that nationalized qualities are very hard-wired for most individuals, likely serving more as predictors of sports media consumption than effects of it. Relationships were also found between nationalized qualities and levels of fan identification toward the U.S. Men’s National Team. Conclusions related to applications to social identity theory and several other potential influences are articulated.

Gender Differences in Introductory Atmospheric and Oceanic Science Exams: Multiple Choice Versus Constructed Response Questions

An analysis of 295 male and 194 female examinations from introductory atmospheric and oceanic science courses is conducted to determine whether or not there exists gender differences in the performance on multiple choice versus constructed response sections of the exams. The difference in the mean performance of males and females on constructed response relative to multiple choice sections of final exams, even in years where the females performed better than or worse than the males on both sections, is on average 5% that is significant at the 0.1% level. Gender differences on time-limited midterm exams are not significant. It is further shown that final exam performance is not significantly related to whether or not the exam starts with a multiple choice versus constructed response set of questions. While our analysis is unable to differentiate between the possibilities that multiple choice questions favor male students and the competing hypothesis that constructed response questions favor female students, existing literature is reviewed to suggest that a combination of both is possible. Nevertheless, from the analysis of our examination results, we can conclude that an exam of introductory atmospheric or oceanic science curricula, which is made up of 60% multiple choice questions and 40% constructed response questions, would not be skewed to favor any particular gender.     

The Great God of the Future: the Views of Current and Future English Teachers on the Place of IT in Literacy

Based on a small but representative study it appears that, in contrast to the past and to some current perceptions, the majority of student teachers and about half of serving teachers of English now welcome information technology (IT) in English and see it as central to the literacy of all pupils. Some current teachers of English remain ambivalent about IT but the general trend is toward a broader definition of literacy in English that gives significant, if not yet equal, value to electronic text alongside the printed word.     

Gender and Dialogue in Secondary School Physics

Previous research points up the educational value of opinion exchange between pupils, particularly in science tasks. However, established gender differences in expression of opinion might well have a substantial impact on such activity, and thus on learning. In order to investigate this, male, female and mixed‐sex pairs of 12‐15 year‐olds were videotaped whilst they worked on a computer‐based task that required them to predict the trajectories of falling objects. All progressed equally in understanding, but employed markedly different interactional styles. Male pairs attended to the implications of feedback for individual ideas, whilst female pairs avoided conflict, exploring instead what the problems had in common. Mixed pairs simply interacted in a very constrained fashion. The differences can be seen as a direct consequence of variation in methods of coping with conflict, compounded, in the mixed groups, by ignorance of the accepted behaviour for the opposite sex. Since male and female patterns separately exhibited characteristics central to scientific method, viz. empiricism and generalisation respectively, broader understanding of science might be served by encouraging each gender to adopt some of the behaviours more ‘natural’ to the other. Practical ways in which this might be achieved are suggested.
