The findings on the association between Social Networking Sites and civic engagement are mixed. The present study aims to evaluate a theoretical model linking the informational use of Internet‐based social media (specifically, Facebook) with civic competencies and intentions for future civic engagement, taking into account the mediating role of civic discussions with family and friends and sharing the news online. Participants were 114 Italian high school students aged 14–17 years (57 % boys). Path analysis was used to evaluate the proposed theoretical model. Results showed that Facebook informational use was associated with higher levels of adolescent perceived competence for civic action, both directly and through the mediation of civic discussion with parents and friends (offline). Higher levels of civic competencies, then, were associated with a stronger intention to participate in the civic domain in the future. Our findings suggest that Facebook may provide adolescents with additional tools through which they can learn civic activities or develop the skills necessary to participate in the future. 相似文献

The proposed assessment sheet aims to show in detail, which qualitative elements of motor performance are performed correctly in the 2nd month of life by children who in the 9th month reached the erect posture. Similar analysis was performed for the qualitative assessment in the 6th month. The prospective investigation of motor development involved a group of 109 children (40 girls and 69 boys). The study was based on the previously described quantity and quality assessment sheet of motor performance, validated for the 2nd and 6th month. Final investigation took place in the 9th month of life and was based on a neurological assessment.It could be shown that a completely correct assessment at the age of 2 months precludes future severe motor development disorders, especially cerebral palsy, although it does not rule out a slight delay. Prematurity and the analyzed risk factors, particularly IVH, impair the motor performance. The absence of axial symmetry, the shoulders protraction and improper position of the pelvis are the most important alarming features at the 2nd month. Distal elements observed in the prone position at the 6th month show a good prognosis for the motor performance in the 9th month. Any abnormalities, mainly related to the body axis and symmetry observed at 2 months of age should encourage one to put a child under observation. 相似文献

Non‐Bayesian Noun Generalization in 3‐ to 5‐Year‐Old Children: Probing the Role of Prior Knowledge in the Suspicious Coincidence Effect 下载免费PDF全文

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum (2007a) suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U‐shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U‐shaped trend. 相似文献

AbstractIn this introduction to the issue Semiotic tools in early mathematical knowledge, we offer a theoretical perspective that provides meaning to the different contributions. We begin by reviewing three perspectives bearing an important influence on the study of mathematical development in childhood (the Piagetian, the information processing and the neonativist perspectives). Next, we underscore the need for developmental studies in this domain to consider the semiotic component, and hence the socio-cultural component, in depth. The contributions that form this volume — a theoretical article, five papers and four short reports of empirical studies and a review of an instructional approach — illustrate different ways of including the semiotic component in the study of children’s mathematical knowledge. 相似文献

Giftedness can be both an asset and a burden when gifted students respond to developmental challenges. Characteristics associated with high intellectual ability likely affect how gifted students experience social, emotional, and career development, regardless of level of academic achievement. Counselors' lack of awareness of such qualitative differences, as well as positive and negative biases, may interfere with the therapeutic relationship. Characteristics related to giftedness, vulnerabilities, concerns, and counseling strategies are the focus of this article. 相似文献

The authors highlight challenges that gifted individuals may encounter in their career development and propose a theory‐informed career counseling framework to help guide them through the process. Special consideration is given to issues that may be salient for gifted individuals in career counseling sessions. Uncontrollable factors that might influence their career decision making, including socioeconomic status, race, gender, and sexual orientation, are also addressed. 相似文献

Community organizers and activists draw on multiple traditions of community building and collective action in attempts to galvanize change. The diversity of perspectives on social change processes indicates corresponding differences in perspectives on systems and what is required to change them. Twenty‐two in‐depth interviews with community organizers and activists in the Midwestern USA were conducted to identify differences in perspectives on systems change efforts. Four models used by organizers were identified: action/issue‐centric, identity‐centric, relationship‐centric, and organizing‐development. Strategies for recruitment, issue selection, leadership determination, and action were compared across models. Analyses revealed that some models might be better suited to action on certain issues (e.g. identity‐centric models when organizing around homelessness), whereas others may have advantages for use in certain settings (e.g. relationship‐centric models in congregations). These findings suggest that practitioners and scholars should pay close attention to contextual factors and focal issues when determining strategies for creating systems change.
