Another Look at What Moves Public Opinion: Media Agenda Setting and Polls in the 2000 U.S. Election     

Son  Young Jun; Weaver  David H. 《Int. Journal of Public Opinion Research》2006,18(2):174-197

This study examined two levels of media agenda effects on aggregatepublic opinion from different news sources. The effects wereinvestigated immediately and cumulatively. Content analysisdata from the 2000 U.S. presidential election coverage by fournational news organizations were related to the Gallup pre-electionpoll standings of each candidate. Regression analyses foundthat both the salience of a candidate and the salience of theattributes of a candidate cumulatively, but not immediately,influenced his standing in the polls. An analysis of news sourcessupported the finding that the two levels of agenda-settingeffects seemed mostly cumulative rather than immediate. Newsfrom different sources, however, tended to have effects of differentdegrees and sometimes different directions on candidate pollstandings. Cumulative effects of candidate salience on aggregateopinion change were found for non-partisan and neutral newssources—reporters, poll reporting and public documents—whereasthe effects of candidate attribute salience mostly came frompartisan sources—the candidate himself and members ofthe competing political party. Possible political implicationsof these findings are discussed.  相似文献   

Peer evaluation: A case study   总被引：1，自引：0，他引：1  

Richard L. Weaver II  Howard W. Cotrell 《Innovative Higher Education》1986,11(1):25-39

Peer evaluation is the process whereby students critique the performances of other students. A peer evaluation format emphasizes skills, encourages involvement, focuses on learning, establishes a reference, promotes excellence, provides increased feedback, fosters attendance, and teaches responsibility. The process of peer evaluation is explained, the criteria are specified, the training for use is described, and how standards are maintained is explained. Finally, objections are suggested and addressed. Peer evaluation is a unique, controlled, and precise form of classroom evaluation that involves carefully constructed evaluation instruments, structured classroom situations, and exact evaluative assessments. Peer evaluation is a new and different form of evaluation.  相似文献

Using 21st century video prompting technology to facilitate the independence of individuals with intellectual and developmental disabilities          下载免费PDF全文

Barriers in acquiring, maintaining, and generalizing daily living skills are factors that contribute to discrepancies in independent living outcomes among transition age youth and young adults with intellectual and developmental disabilities (IDD). Acquisition and generalization of daily living skills empowers transition age youth and young adults with disabilities to meet their own needs with minimal reliance on others. Infusing the use of technology as a self‐prompting device facilitates the acquisition of tasks that may not be otherwise attainable. In this study, self‐directed video prompting on an iPad with the My Pictures Talk application was used to help young adults with IDD in a postsecondary program acquire daily living skills in a single subject, multiple probe across subjects design. The effects of the intervention on generalization to tasks that were one, two, and three components different were also assessed. Results demonstrated a functional relationship between the introduction of the intervention and improvement in skill performance.  相似文献   

Real time search on the web: Queries,topics, and economic value     

Bernard J. Jansen  Zhe Liu  Courtney Weaver  Gerry Campbell  Matthew Gregg 《Information processing & management》2011

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source.  相似文献

What do they know?: An assessment of undergraduate library skills     

Lilith R. Kunkel  Library Director  Susan M. Weaver  Library Director  Kim N. Cook  Library Director 《The Journal of Academic Librarianship》1996,22(6):430-434

This article, which examines variables affecting scores on a test of library skills, finds that the frequency with which students receive assignments requiring library research is the best predictor of a score. The unevenness is students' research skills has implications for bibliographic instruction.  相似文献   

Physics Courses in the New Arizona Engineering Curriculum     

Weaver  A. B. 《Education, IRE Transactions on》1959,2(4):117-120

To facilitate the adoption of a common core curriculum in the Schools of Engineering and of Mining at the University of Arizona, the general physics course for engineers has been dropped. The physical foundation for engineering is taught in a new series of courses in the Civil, Mechanical, Electrical Engineering, and Physics Departments as part of the common core. The Physics Department teaches atomic, molecular, nuclear, and solid-state physics in a seven-unit junior-level course. There are grounds for a re-examination of the role of physics in engineering education and perhaps for extensive changes. It is suggested, however, that the role is, and should remain, vital, in the interests of science, of engineering, and of education.  相似文献   

Characteristics of child abuse in immigrant Korean families and correlates of placement decisions     

Chang J  Rhee S  Weaver D 《Child abuse & neglect》2006,30(8):881-891

OBJECTIVE: This study examined the characteristics and patterns of child abuse among immigrant Korean families in Los Angeles and critical variables that contribute to the type of placement made by the child protective services (CPS) system. METHOD: Data were obtained from reviewing and analyzing 170 active Korean case files maintained by the Asian Pacific Unit (APU) of the Los Angeles County Department of Children and Family Services (LAC-DCFS) during July through September, 2001. Logistic regression analysis was employed to examine the odds of children being kept in or removed from the home. RESULTS: Some of the major findings from this study include: (1) immigrant Korean families are more likely to be charged with physical abuse (49.4%) and less likely to be charged with neglect (20.6%) in comparison with all other groups in Los Angeles (13.2% and 27.1%, respectively); (2) the circumstance under which physical abuse occurred most frequently was corporal punishment used by Korean parents with an intention to discipline their children; and (3) the context under which emotional abuse occurred among the Korean families was likely to be children's witnessing domestic violence. In addition, the logistic regression showed that response status, referral source, living arrangement, victim's relationship to perpetrator, and chronicity of abuse were significant in predicting out-of-home placement. CONCLUSIONS: An analysis of Korean child abuse cases reported to child protective service revealed that culture and child rearing practices shaped the patterns of child maltreatment. A culturally sensitive approach is strongly suggested for effective child abuse prevention and intervention services with this group by CPS agencies.  相似文献
