The Role of Practicality in the Choice of Instructor Rating Methods   总被引：1，自引：0，他引：1  

Norbert F. Elbert  Carol Saunders  Jason Schweizer 《Journal of Experimental Education》2013,81(3):114-121

Behavioral Expectation Scales (BES) were compared to summated and trait-oriented scales as measures of teaching performance. The scales were developed in a college setting; the ratees were college professors and their raters were college students. Both the psychometric properties and the practicality criterion were examined. Overall, the psychometric evidence suggests that the summated format is slightly superior. When the issue of practicality is examined in terms of the raters’ perceptions of which method is easiest, most difficult, most defensible, and most accurate, the summated scale is definitely superior. Surprisingly, even the students who participated in the development of the BES format preferred the summated form. Given the inconclusive psychometric evidence reported in the literature, and until better tests are formulated, it appears that the deciding factor will ultimately depend on what we believe is the neglected criterion of practicality.  相似文献

Behavioral control and resiliency in the onset of alcohol and illicit drug use: a prospective study from preschool to adolescence   总被引：4，自引：0，他引：4

The developmental trajectories of behavioral control and resiliency from early childhood to adolescence and their effects on early onset of substance use were examined. Behavioral control is the tendency to express or contain one's impulses and behaviors. Resiliency is the ability to adapt flexibly one's characteristic level of control in response to the environment. Study participants were 514 children of alcoholics and matched controls from a longitudinal community sample (Time 1 age in years: M =4.32, SD =0.89). Children with slower rates of increase in behavioral control were more likely to use alcohol and other drugs in adolescence. Children with higher initial levels of resiliency were less likely to begin using alcohol.  相似文献   

Characterising the impact performance of field hockey sticks   总被引：1，自引：1，他引：0  

Tom Allen  Leon Foster  Matt Carré  Simon Choppin 《Sports Engineering》2012,15(4):221-226

Published research on field hockey equipment is scarce. The aim of this research was to investigate methods for characterising the impact performance of field hockey sticks. Three sticks were used with fundamental frequencies in the range 74?C154?Hz. Striking an initially still ball with a stick was identified as the preferred method for characterising performance. Impacts were simulated at mean velocities of 19?m/s at toe and 16?m/s at the shaft. The mean apparent coefficient of restitution and standard deviation were ?0.32?±?0.05 at the toe and ?0.18?±?0.02 at the shaft. The foundation work presented here provides the foundations for developing a methodology for characterising the impact performance of field hockey sticks.  相似文献

Perspectives on Accreditation and Information Literacy as Reflected in the Literature of Library and Information Science     

Laura Saunders   《The Journal of Academic Librarianship》2008,34(4):305-313

Regional accreditation organizations increasingly include student learning outcomes for information literacy in their standards and other documents, often emphasizing the importance of collaboration between librarians and faculty. Through content analysis of published articles and listserv postings, this study analyzes how librarians acknowledge such accreditation organizations in the context of information literacy.  相似文献   

TweetStorm in #ferguson: How News Organizations Framed Dominant Authority,Anti-Authority,and Political Figures in a Restive Community     

Ginger E. Blackstone  Holly S. Cowart  Lynsey M. Saunders 《广播与电子媒介杂志》2017,61(3):597-614

After Officer Darren Wilson fatally shot African American teen Michael Brown in August 2014, rioters unleashed their anger on the streets of Ferguson, Missouri. Using content analysis and framing theory, this study analyzed how news organizations covered events in Ferguson on Twitter over the course of a month immediately following the shooting. Protesters were framed as troublemakers; but community leaders were not framed as “rabble-rousers.” Journalists continued to rely on official sources more than alternate sources in spite of criticism of law enforcement and other political elites, but nearly 10% of the coded tweets that relied on official sources included some element of skepticism. Tweets from cable news outlets did not show partisan bias in any significant amount; and traditional legacy news media sources utilized the Twitter platform enhancements—such as article links, photos, links to other content, or hashtags—more than their new digital media counterparts. As Twitter launched #ferguson into the national consciousness, it is quite plausible that the framing of the tweets by news agencies may have molded perceptions of larger issues about the racial health of the nation, established policies of law enforcement, and the challenge of elected leaders to resolve explosive domestic problems.  相似文献
