Rapid advances in technology have provided the potential to connect citizens to their surroundings in unprecedented ways. While many scholars examine different types of efficacy as a predictor of behavior (e.g., internal, external, and political), it is essential to examine how confident citizens feel in their ability to use the technology before understanding how they will use it politically. Research shows that perceived competence increases motivation, which is correlated with behavior. This study examined how traditional measures of efficacy and a new measure affect online political behaviors, concluding that technological efficacy is a reliable construct predicting online news use and expression.  相似文献

Attachment and Adolescent Psychosocial Functioning   总被引:8,自引:1,他引:8  
To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Security displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analyses. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development.  相似文献

This article compares the examination performance of students following General Certificate of Secondary Education Applied Science and Double Award science on a value‐added basis. It uses data from the National Pupil Database, which are analysed by a variety of methods, including multilevel modelling. It argues that the claims made within Office for Standards in Education reports on the impact of the new Applied Science course are inaccurate, and in some cases positively wrong. The authors' analysis, based on the second (2003–05) cohort of students following the course, shows that students of lower attainment at Key Stage 3 appear to perform better than would have been predicted from their Key Stage 3 attainment, but that higher attaining pupils perform less well. Schools offering Applied Science show greater diversity in the value‐added effects they produce than they do with Double Award science. The article argues that analyses of this kind are of value in seeking to understand the impact of curriculum reform, but that they are dangerous as a generalized guide for policy. They must be complemented by work in schools in which the sources of the effects observed and of school diversity are examined.  相似文献

In oral language, morphologically conditioned regularities around stress assignment can be found in two classes of derivational suffixes, one that causes lexical stress to shift to the syllable immediately preceding the suffix (ACtiveacTIVity) and one that has no effect on stress (SILLySILLiness). In this study, adults listening to spoken “derived” nonwords judged as preferable those wherein the stress placement was consistent with morphological regularities of English. When reading nonwords and a set of nonwords derived from them, readers reliably assigned stress to the syllable predicted by the morphology. This effect was significantly associated with scores on standardized measures of word reading after controlling for nonword reading ability, showing that the relationship was not merely an artifact of decoding skill. These findings support the importance of the interface between morphology and suprasegmental phonology as a key factor in the way English-speaking readers approach multisyllabic, morphologically complex words.  相似文献

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data. This simple approach relies on fewer assumptions and yet can result in policy-relevant findings. As we show, even moderately predictive covariates can be used to substantially tighten bounds in a straightforward manner. Via simulation, we demonstrate which types of covariates are maximally beneficial. We conclude with an analysis of a multisite experimental study of Early College High Schools. When examining the program's impact on students completing the ninth grade “on-track” for college, we find little impact for ECHS students who would otherwise attend a high-quality high school, but substantial effects for those who would not. This suggests a potential benefit in expanding these programs in areas primarily served by lower quality schools.  相似文献
