The current study examines adolescents’ interpretations of a televised scene narrative describing a sexual initiation encounter. The study uses the media practice model as a theoretical framework. Two hundred ninety-three 10th, 11th, and 12th graders suggested possible endings to the narrative, reflecting their outcome expectancies for sexual initiation. The adolescents’ suggested scene endings were divided into 10 categories, including emotional, physical, and relational outcomes. A thematic analysis of their outcome expectancies revealed some shared themes, but important individual differences based on gender and sexual experience also were identified, consistent with media practice model assumptions. Male students were more technical and less emotional than female students in their scene interpretations. Adolescents without sexual experience suggested more simplistic and deterministic outcomes than more sexually experienced teens. The study contributes to the understanding of adolescents’ interpretation of mediated narratives in the context of sexual initiation and supports their complex, active, and developmentally consistent understanding of this topic. 相似文献

This article examines the strategies and practices by which the Israeli news media negotiated and (re)appropriated a Lebanese documentary that was produced in cooperation with a French company and was purchased and broadcast by an Israeli commercial channel. Using this transnational textual event, the article explores the dynamics, opportunities and pitfalls associated with transcultural exchanges that take place in a conflictual, translocal context, and the ways in which such exchanges are shaped by an interplay of material-institutional and discursive-symbolic dimensions. The article also provides a multi-layered framework for analyzing the broadcasting and journalistic practices surrounding such textual events, and establishes the relationship between appropriation and witnessing strategies. I show how the Israeli media—driven by commercial interests and applying complex forms of witnessing and appropriation—worked to sustain national myths and suppress the potentially disruptive aspects of the documentary, while at the same time exposing the weaknesses of these myths, as well as the limits of the State's power. Emerging from this case study is a complex picture of the multifaceted roles played by national news media in a transnational economy, and of the ways in which commercial media interests serve as both hegemonic and disruptive forces within the context of the Israeli-Arab conflict. 相似文献

This paper examines the portrayal of sexual messages in the top 20 most popular television programs among teenagers in the United States. It compares findings from the 2001–2002 and 2004–2005 seasons. Results show that these programs contained a large number of sexual messages, though their frequency decreased over time. Most messages about sex were in the form of conversations. About 1 in 2 shows included portrayals of sexual behaviors, mostly precursory behaviors. Sexual risk and responsibility concerns were rarely addressed. Most consequences for sexual intercourse portrayed in 2004–2005 were negative, a significant change from 2001–2002. The findings' implications for adolescents' sexual socialization are discussed. 相似文献

We propose and evaluate a framework supporting collaborative discovery learning of complex systems. The framework blends five design principles: (1) individual action: amidst (2) social interactions; challenged with (3) multiple tasks; set in a (4) a constrained interactive learning environment that draws attention to (5) highlighted target relations. The framework addresses a persistent tension in discovery-based pedagogy between offering students the freedom to initiate, experiment, and explore and providing them with tailored experiences with many instances of particular relations underlying the target conceptual structure. The framework was realized with TrafficJams, a participatory simulation in which students drive together. A class of high-school students worked with TrafficJams over 2.5 h. The teacher’s role was to orchestrate the activity but there was no explicit instruction of the traffic and complexity principles. The students completed pre- and post-test questionnaires and their activities were observed and logged. In terms of driving in the simulation, the students learned to drive in ways that reduced congestion in traffic by decreasing lane and speed changes, and keeping their speed down. Even though there was no explicit teaching, half of the students learned that car speed distribution alone can generate traffic jams with no additional causes; and, keeping a safe following distance from the next driver increases everyone’s speed. Our study suggests that the learning environment partially met both the overarching design goal of constrained discovery and the specific content goal of systems reasoning. 相似文献

A child's first words mark the emergence of a uniquely human ability. Theories of the developmental steps that pave the way for word production have proposed that either vocal or gestural precursors are key. These accounts were tested by assessing the developmental synchrony in the onset of babbling, pointing, and word production for 46 infants observed monthly between the ages of 9 and 18 months. Babbling and pointing did not develop in tight synchrony and babble onset alone predicted first words. Pointing and maternal education emerged as predictors of lexical knowledge only in relation to a measure taken at 18 months. This suggests a far more important role for early phonological development in the creation of the lexicon than previously thought. 相似文献

Wi-Fi radiation is a type of radio frequency electromagnetic radiation (RF-EMR) that refers to the transfer of energy by radio waves. Nowadays, exposure to RF radiation is widespread including wireless internet connection (Wi-Fi) routers and cell phones. The proliferation of devices emitting RF radiation has entailed some public and media-generated controversy, although scientific evidence has not pointed to the existence of risk. Using the theoretical perspectives of science literacy, public engagement with science, and science media literacy, this work examines public engagement with science-related media reports in a context involving risk. A qualitative design was followed to address multiple viewpoints including an analysis of an authentic primetime TV program concerning the risks of Wi-Fi, its messages, and frames, solicited a public response to the coverage via interviews and decision-making simulation (n = 20), and unsolicited public response based on social media discussions (n = 315 comments). Our findings suggest that a lack of relevant scientific knowledge does not seem to be related to participants’ general scientific literacy among people with higher education. Moreover, interviewees did not place much emphasis on having adequate knowledge in making their decision. These findings emphasize that we need to expand our understanding of the different ways that make scientific knowledge relevant when making decisions on scientific issues that relate directly to everyday life.

ABSTRACTWill open education replace traditional higher education, or augment it? Digital innovation in the higher education sector is fuelling speculation about the transformation of higher education and the future role of universities. Much of the speculation makes questionable implicit assumptions about current and future business models in the higher education sector. This conceptual paper applies an innovation management perspective to critically examine the use and misuse of the business model concept in the context of digital innovation in the higher education sector. Using Raymond’s metaphor of the cathedral and the bazaar which contrasted traditional commercial software development (the cathedral) with open source software development (the bazaar). We analogise this relationship with the relationship between ‘cathedral-type’ business models in traditional higher education (e.g. universities) and ‘bazaar-type’ business models in open education (e.g. open educational resource publishers). Using the historical perspective we now have on the software industry’s evolution we critique the ubiquitous replacement narrative of destruction and disruption of the sector, and propose an alternative narrative of interdependence and mutual innovative catalysis. We predict that higher education ecosystems will be based on synergistic relationships between organisations that represent many gradations on the continuum between ‘cathedral-type’ and ‘bazaar-type’ organisations. 相似文献

This article reports the results of a survey of the reading habits and interests of immigrants in Toronto who speak Russian as their first language, including their use of Canadian public libraries, ethnic and English-language bookstores, and their attitudes toward collecting books at home. The survey results show that Russian Canadians use the public library system extensively and for diverse purposes. They also make use of ethnic and English-language bookstores, purchasing materials in both Russian and English for leisure reading, educational and professional development, and expansion of their highly valued home collections. The peculiarities of the demands and behavior of first generation Russian-speaking immigrants are also discussed, especially with regard to changes in reading interests and attitudes associated with immigration, as well as the problems experienced by public libraries in meeting the needs of this clientele. Finally, recommendations for the improvement of public library services and collections for this linguistic group are provided. 相似文献
