Direct and Indirect Effects of Involvement on Hostile Media Perceptions in the Context of the Refugee Crisis in Germany and Switzerland     

Dorothee Arlt  Caroline Dalmus  Julia Metag 《Mass Communication and Society》2019,22(2):171-195

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   

New insights into family learning for refugees: bonding,bridging and building transcultural capital     

Julia Hope 《Literacy》2011,45(2):91-97

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

Age and sex influences on running mechanics and coordination variability     

Katherine A. Boyer  Julia Freedman Silvernail  Joseph Hamill 《Journal of sports sciences》2017,35(22):2225-2231

The purpose of this study was to examine the impact of age on running mechanics separately for male and female runners and to quantify sex differences in running mechanics and coordination variability for older runners. Kinematics and kinetics were captured for 20 younger (10 male) and 20 older (10 male) adults running overground at 3.5 m · s^?1. A modified vector coding technique was used to calculate segment coordination variability. Lower extremity joint angles, moments and segment coordination variability were compared between age and sex groups. Significant sex–age interaction effects were found for heel-strike hip flexion and ankle in/eversion angles and peak ankle dorsiflexion angle. In older adults, mid-stance knee flexion angle, ankle inversion and abduction moments and hip abduction and external rotation moments differed by sex. Older compared with younger females had reduced coordination variability in the thigh–shank transverse plane couple but greater coordination variability for the shank rotation–foot eversion couple in early stance. These results suggest there may be a non-equivalent aging process in the movement mechanics for males and females. The age and sex differences in running mechanics and coordination variability highlight the need for sex-based analyses for future studies examining injury risk with age.  相似文献   

Writing week-journals to improve the writing quality of fourth-graders’ compositions     

Pedro Rosário  Julia Högemann  José Carlos Núñez  Guillermo Vallejo  Jennifer Cunha  Vera Oliveira  Sonia Fuentes  Celestino Rodrigues 《Reading and writing》2017,30(5):1009-1032

Students’ writing problems are a global educational concern and is in need of particular attention. This study aims to examine the impact of providing extra writing opportunities (i.e., writing journals) on the quality of writing compositions. A longitudinal cluster-randomized controlled design using a multilevel modeling analysis with 182 fourth grade students was conducted. We examined whether students’ writing quality differed when writing journals on a weekly basis for 12 weeks, compared with a control group. Three covariates were analyzed, namely: (i) the students’ attitudes towards writing; (ii) their self-efficacy in writing; (iii) and their use of self-regulation (SRL) strategies while writing. Findings have shown that students who wrote week-journals significantly improved the writing quality of their compositions and reported a higher use of SRL strategies in writing. Nevertheless, self-efficacy and attitude towards writing were found to not be related to the quality of the compositions. Moreover, data indicated that the writing quality of compositions improved along with the writing quality of the week-journals. Findings suggest the use of week-journals in class to promote writing.  相似文献   

Can Children With Autism Spectrum Disorders “Hear” a Speaking Face?     

Irwin JR  Tornatore LA  Brancazio L  Whalen DH 《Child development》2011,82(5):1397-1403

This study used eye-tracking methodology to assess audiovisual speech perception in 26 children ranging in age from 5 to 15 years, half with autism spectrum disorders (ASD) and half with typical development. Given the characteristic reduction in gaze to the faces of others in children with ASD, it was hypothesized that they would show reduced influence of visual information on heard speech. Responses were compared on a set of auditory, visual, and audiovisual speech perception tasks. Even when fixated on the face of the speaker, children with ASD were less visually influenced than typical development controls. This indicates fundamental differences in the processing of audiovisual speech in children with ASD, which may contribute to their language and communication impairments.  相似文献   

‘Learning Experience’ Provided by Science Teaching Practice in a Classroom and the Development of Students’ Competences     

J. Bernardino Lopes  Julia Branco  Maria Pilar Jimenez-Aleixandre 《Research in Science Education》2011,41(5):787-809

According to the literature, there is a very important corpus of knowledge that allows for the investigation of some dimensions of ‘learning experience’ provided to students, in relation to epistemic, pedagogical and meta-cognitive practices. However, in the literature, there is little investigation into the invariance (or not) of the characteristics of students’ learning experience while being taught a scientific subject by the same teacher. This paper suggests that the relationship between the learning experience provided and the competences developed is not properly highlighted. This paper analyses the learning experience provided to students in epistemic, pedagogical and meta-cognitive terms. The students were taught the proprieties and applications of light by one teacher, in three classes, over 7 weeks. We analysed the data in each referred learning experience, using a pre-defined category system. The students’ competences were evaluated by a competence test. The epistemic demand of each item and the students’ performances were also analysed. Our findings point to the non invariance of learning experiences provided to students and the influence of some dimensions of learning experiences provided in the development of certain competences. These findings and their implications are contextualized and discussed.  相似文献
