American television programs have been criticized for being filled with images endorsing capitalist consumerism and for being weighted toward the upper middle classes. This study proposed that heavy viewing of these distorted representations may culminate in decreases in viewers' life satisfaction. A path model investigated this supposition, based on material value and social comparison perspectives. Surveys were administered to 225 adults in a northeastern town in the United States, and the data were subjected to path analysis. The findings of this study suggest that heavy television viewing may be associated with material value, estimates of other people's affluence, and perceived gaps between the self and others in material affluence. Of importance, the findings also suggest that the perceived gaps between the self and others may be associated both with dissatisfaction with personal life and dissatisfaction with current social equality, whereas material value may be associated only with dissatisfaction with personal life. 相似文献

Since its inception in 2002, COUNTER has given hope to many librarians charged with collecting usage data for their online collections. This hope turned to optimism in 2007 with the release of SUSHI (Standardized Usage Harvesting Initiative) as a NISO standard (Z39.93). In 2009 release 3 of the COUNTER Code of Practice for Journals and Databases takes effect and with it are some significant advances that will turn hopes and optimism into realities. This article describes the changes and their implications. 相似文献

Ever since OpenURL linking was introduced in 2000 by Herbert van de Sompel the link resolver has played an important role in providing users with access to the online resources they have rights to. From the start, one of the criticisms of OpenURL linking has been that it is not 100% successful—sometimes the user is presented with a link to full text, but that link fails. In 2010 a new National Information Standards Organization (NISO) workgroup was created to tackle the issue of OpenURL quality. This column will discuss this NISO initiative and look in detail at the proposed “Completeness Index” that promises a means of measuring the quality of OpenURLs being submitted by various content providers. The article will also discuss how some OpenURL quality issues may be more perception than reality and how librarians can configure their links and link resolvers to overcome these negative perceptions. 相似文献

ONIX for Publication License (ONIX-PL) was introduced in 2006 with great hope that it would simplify the licensing and license management aspects of e-resource management. However, after several years this standard has not seen significant commercial adoption. Believing this standard still holds promise, the National Information Standards Organization, with funding from the Andrew W. Mellon Foundation and support from Jisc and EDItEUR, has launched the ONIX-PL License Encoding Project. The goal of the project is to accelerate adoption by creating and making publicly available a set of publisher licenses encoded to the ONIX-PL standard. In this column we provide more details on the project, its goals, challenges, and prospects. 相似文献

The Counting Online Usage of Networked Electronic Resources (COUNTER) Code of Practice and Standardized Usage Statistics Harvesting Initiative (SUSHI) are two standards whose successful adoption will greatly assist librarians in performing accurate and timely usage analysis of their online collections and thus make more informed collection management decisions. Variations in how these standards have been applied by content providers to their SUSHI and COUNTER implementation are currently impacting their widespread adoption. The standards themselves are not broken—what is needed is concise guidelines on their implementation. This column reviews some of the roadblocks that impede consistent implementation of these standards as well as proposes recommendations that could form the basis of a community profile for these standards. 相似文献

Interest in inquiry-based science education (IBSE) often pays little heed to the complex power relations that exist within classrooms. A common obstacle to inquiry is that it strongly diverges from current classroom culture and hence, is outside the sphere of teachers' and students' experiences. Teachers and students bring expectations to the classroom that are entrenched in traditional practices and influenced by dynamics of power that exist within all teacher–student relationships. This study, which emerged during a wider study of the use of a Virtual Chemistry Lab in supporting IBSE, explores how classroom discourse constructs and maintains power relations that either stifle or facilitate inquiry-based approaches in two science lessons. Research methods included teacher interviews, student focus groups, video-recorded lessons, and student self-assessments. Findings indicate distinctive features of power inside the classroom that impact on inquiry-based instruction, such as predominant teacher monitoring on task completion over task understanding, lack of student engagement in ownership of scientific ideas, and prevailing norms of what effective teacher questioning is. We discuss implications for IBSE change efforts, highlighting that well-established power relations currently represent an important limiting factor in the capacity of teachers' IBSE implementation. 相似文献

Abstract Educators have invested considerable effort in developing environmental education programs that address students' knowledge, attitudes, and action competence regarding environmental issues. The authors explore the effectiveness of such programs in terms of both student learning outcomes and the intergenerational influence that results when students discuss their learning experiences with their parents and other community members. Six environmental education programs involving 284 students in Queensland schools, from Grades 5-12, were investigated. Students and their parents were surveyed and interviewed regarding their perceptions about the program, the program's influence on their environmental learning, and the extent and nature of discussions that the program stimulated between students and their parents. The authors draw conclusions about key features that should be incorporated into environmental education programs to encourage and empower students to bring about environmental change in their homes and communities. 相似文献

On August 8, 1974, having been toppled from power by the Watergate scandal, Richard M. Nixon became the first President to resign his office before completing his term. In his resignation speech, Mr. Nixon attempted to vindicate himself before the American people. Analysis of Mr. Nixon's address reveals that his strategies of denial of intent and transcendence to a larger context were largely unsuccessful in securing closure with his audience. 相似文献

Creative activities are a challenge for long-term care facilities. The Passport intervention uses web-based video technology to provide long-term care residents with a virtual travel experience. Passport broadcasts were conducted and staff and residents were interviewed about the experience. A thematic analysis of interviews was used to discern benefits and challenges. Reported benefits included experience with technology, interaction with student visitors, reminiscing, and active learning. Challenges involved technical quality concerns related to the audio and visual needs of seniors. The pilot found the Passport intervention as a promising tool for creative activities in a long-term care setting. 相似文献
