The widespread use of handheld computers and other mobile devices in the healthcare environment and their potential for providing access to information has prompted health sciences librarians everywhere to learn more about this technology. Early in 2001, the Health Sciences Library (HSL) at the University of North Carolina at Chapel Hill began exploring ways to support mobile computing. This paper describes the four basic approaches taken by the librarians that helped establish the HSL as a leader in the area of mobile technologies. 相似文献

Previous research has indicated that the keyword method of vocabulary learning facilitates students' performance not just on simple tests of definition recall, but on comprehension-demanding tasks as well. The present study was conducted to determine whether the “comprehension” finding could be accounted for by keyword subjects' superior definition recall per se. The results generally supported that conclusion: When conditions and subjects within conditions were equated with respect to their initial levels of definition recall, the comprehension advantage of keyword subjects disappeared. 相似文献

This article examines hostile media perceptions (HMPs) by building on recent trends in hostile media research. Our study considers the effects of people’s cognitive as well as their affective involvement on HMPs. As the media landscape has changed fundamentally since HMPs were initially identified, the role of social media is explored more profoundly. In addition, this article not only examines the direct effects of involvement and communication activities but tests for indirect effects of involvement mediated through media use and interpersonal discussions. Using data simultaneously collected from two online surveys conducted in Germany and the German-speaking part of Switzerland, the findings strengthen previous evidence that affective involvement is a stronger predictor of HMPs than cognitive involvement. In contrast, media use and interpersonal discussions had only marginal direct effects. The study provides initial evidence for the indirect effects of involvement mediated through exposure to online user comments and interpersonal discussions. 相似文献

For over 20 years, researchers and evaluators worldwide have criticised the traditional formula of family learning courses for their narrow vision, and have emphasised their potential to provide a bridge between home and school experiences, building on resources that parents already have, but which are unknown or unacknowledged. This article argues that research into family learning can usefully be linked to Bourdieu's theory of ‘symbolic capitals’ to acknowledge the stores of wealth that refugee families may possess, which can be activated in the new environment to create ‘transcultural capital’– a relatively new concept in the area of migration studies. Putnam's notions of bonding and bridging capital are also helpful in the design of family learning programmes to consider how best to stimulate social cohesion at the present time. An ethnographic study of a family learning course for refugee parents in two South London schools highlights the need for an understanding of the specific strengths and needs of refugee parents. However, this can only be achieved by taking time to find out about their existing networks, the experience that they bring with them, involving them in course design and delivery, and engaging in discussion about their plans for the future. 相似文献

Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White; collected from 2007 to 2017 near Philadelphia) were analyzed at 6, 12, and 24 months. At 12 months, HR-ASD infants produced fewer vocalizations than HR-Neg infants. From 6 to 24 months, HR-Neg infants demonstrated steeper vocalization growth compared to HR-ASD and LR infants. Finally, among HR infants, vocalizing at 12 months was associated with language, social phenotype, and diagnosis at age 2. Infant vocalizing is an objective behavioral marker that could facilitate earlier detection of ASD. 相似文献
