This paper assesses how use of smartphones relates to exposure to heterogeneity, political efficacy, and political engagement and suggests a new mediation model that can be applied to mobile communication. Drawing on online survey data collected during the 2012 presidential election in South Korea, this study finds that exposure to heterogeneity and political efficacy jointly mediate the impact of informational uses of smartphones on political participation. The current study also shows that informational uses of smartphones are significantly related to encounters with heterogeneity, political efficacy, and participatory behaviors. Additionally, recreational uses of smartphones were found to have a positive association with exposure to heterogeneity. However, relational uses of smartphones were not associated with democratic outcomes. The findings suggest that smartphones, by increasing the possibility of encountering diversity and subsequently enhancing political efficacy, create an additional pathway to citizen engagement in democratic processes. 相似文献

The EIAH Metadata Application Profile (EMAP) has been designed to meet Encyclopedia of Iranian Architectural History (EIAH) needs regarding the organization of architectural resources. The application profile should satisfy community needs and should respect existing conventions; architects may think differently from archivists or museum curators. The key issues in the design process have been addressed here; namely, compliance with the special needs of EIAH data architecture, interoperability, compliance with Persian language and localization, as well as simplicity, critical because of the wide range of non-cataloger users of the system. The EMAP has been designed based on Dublin Core; six element refinements have been defined for the Dublin Core element “subject” to facilitate the interconnection of resources to entities in the EIAH ontology. In particular, human readable documentation guidelines have been emphasized as an important factor in metadata quality. Metadata crosswalks have also been defined with major standards of the domain to improve interoperability. 相似文献

This study examined the impact of a 15-min daily explicit vocabulary intervention in Spanish on expressive and receptive vocabulary knowledge and oral reading fluency in Spanish, and on language proficiency in English. Fifty Spanish-speaking English learners who received 90 min of Spanish reading instruction in an early transition model were randomly assigned to a treatment group (Vocabulary Enhanced Systematic and Explicit Teaching Routines [VE-SETR]) or a comparison group that received general vocabulary instruction using the standard reading curriculum with general strategies designed to increase the explicitness of instruction (General Systematic and Explicit Teaching Routines). Results indicated a statistically significant difference in depth of student Spanish vocabulary knowledge favoring the VE-SETR group. Differences on language proficiency in English, general vocabulary knowledge in Spanish, and oral reading fluency in Spanish were not statistically significant. Implications for future research are discussed. 相似文献

Atomic theory or the nature of matter is a principal concept in science and science education. This has, however, been complicated by the difficulty students have in learning the concept and the subsequent construction of many alternative models. To understand better the conceptual barriers to learning atomic structure, this study explores the troublesome nature of this fundamental scientific concept. In order to illustrate the distinction of student understanding by threshold barriers, this study chose three particularly high‐achieving students from an original interview sample of 20 students who were selected from an introductory college chemistry course. The pre‐course and post‐course interview responses were examined and compared in detail. This study considers the concepts of ‘probability’ and ‘energy quantization’ to both describe the structure of the threshold of understanding students’ need to negotiate in their construction of the target model of atomic structure. In this respect, this study suggests atomic structure as a possible threshold concept for further study in science. Identifying the nature and structure of the threshold of understanding confronting students, and analyzing the troublesomeness of atomic structure, provides valuable information for understanding student learning difficulties, and insight into how they may be addressed. 相似文献

This study examined whether gaining access to a new digital device enhanced the digital media literacy of young adults and what factors determine such change. Thirty-five young adults were given a mobile tablet device and observed for one year. Participants engaged in an online community, responding regularly to online surveys and discussion forums. Digital media literacy, using multidimensional scales, was measured at the beginning and end of the study. Usage was measured every month to track changes over time. When measured with multiple dimensional scales, the participants’ digital media literacy levels increased over time. Those who used the tablet device for information access and social activities increased their digital media literacy in some dimensions. However, an increase in digital media literacy was not directly related to the time spent on the tablet. 相似文献

Love Styles and Communication in Relationships: Partner Preferences,Initiation, and Intensification 总被引:1,自引:1,他引:0

The three exploratory studies reported here investigate the role of love styles in the early stages of romantic relationships. Study 1 (N = 108) had subjects rate and rank 14 characteristics of prospective romantic partners. As expected, individual's love style scores were related to the characteristics people report as desirable in a relational partner. Several of these effects, however, were moderated by sex. Study 2 (N = 173) revealed that scores on love styles were associated with ratings of opening lines and intensification strategies. None of these effects were moderated by sex. Study 3 (N = 137) investigated the association between love styles and ratings of secret tests among individuals currently involved in a romantic relationship. The results indicated that love styles were associated with ratings of secret tests. These data add to a growing body of literature suggesting that love styles are associated with individual differences in relational and communicative behavior across the life span of romantic relationships. 相似文献

Many countries design and implement school change with a focus on the fundamental reconfiguration in the structures of schooling. In this article, we examined the relationship between principal leadership and teacher resistance to school reforms driven by external interveners. For an empirical analysis, we took advantage of extensive data derived from 967 teachers and 32 principals in Korean vocational high schools that are now experiencing school reforms launched by the government. Our results revealed the importance of human aspects of school changes and reforms, in particular, driven by the external intervener. We first showed that a principal's initiative leadership is significantly related to the reduction of teacher resistance to change, in particular on the emotional and behavioural dimensions. Not surprisingly, teachers showed a higher level of resistance when their schools participate in the government-driven reform. Finally, teacher resistance depended upon characteristics of teachers as well as principals. These findings provide some useful policy implications for facilitating successful school reform efforts. Foremost, school reformers are advised to rethink the school change model design in a way of fully capturing human aspects in the reform process. 相似文献

This article explores the limits of introductory social justice education and the ways in which a social foundations course could expand and deepen the social justice lens of current and future educators. The authors, members of an introductory graduate-level Social Foundations course, discuss the limitations they realized in their previous social justice education courses, and the importance of courses that further student's understandings of the ever-evolving ways people enact and experience identity, power, and privilege. The authors identify three main pedagogical and theoretical elements that advanced their social justice knowledge: examining theories for their potential to uncover or obscure lived experience; unpacking binary constructions of identity; and exploring the limits and possibilities of intersectional thinking. This article offers implications and suggestions for educators who seek to challenge and expand the social justice knowledge of future educators and administrators. 相似文献
