Assessing Model Similarity in Structural Equation Modeling     

Keke Lai  Samuel B. Green  Roy Levy  Ray E. Reichenberg  Yuning Xu  Marilyn S. Thompson 《Structural equation modeling》2016,23(4):491-506

Two models can be nonequivalent, but fit very similarly across a wide range of data sets. These near-equivalent models, like equivalent models, should be considered rival explanations for results of a study if they represent plausible explanations for the phenomenon of interest. Prior to conducting a study, researchers should evaluate plausible models that are alternatives to those hypothesized to evaluate whether they are near-equivalent or equivalent and, in so doing, address the adequacy of the study’s methodology. To assess the extent to which alternative models for a study are empirically distinguishable, we propose 5 indexes that quantify the degree of similarity in fit between 2 models across a specified universe of data sets. These indexes compare either the maximum likelihood fit function values or the residual covariance matrices of models. Illustrations are provided to support interpretations of these similarity indexes.  相似文献   

Learning through discussions   总被引：1，自引：1，他引：1  

Robert A. Ellis  David Levy  Kelvin Tan 《高等教育研究与发展》2004,23(1):73-93

Students studying a third‐year e‐commerce subject experienced face‐to‐face and online discussions as an important part of their learning experience. The quality of the students' experiences of learning through those discussions is investigated in this study. This study uses qualitative approaches to investigate the variation in the students' understanding of what they were learning through discussions, and how they went about engaging in them. Quantitative analyses are used to investigate how the students' experience related to their performance. Key outcomes of the study include that the quality of the students' experience of learning through discussions is positively related to their performance and that face‐to‐face and online discussions have qualitatively different benefits for learning.  相似文献   

New “Starting Points” for Resources by Subject     

Katherine A. Prentice  Julie K. Gaines  Linda S. Levy 《Medical reference services quarterly》2013,32(1):88-97

The objective of the Starting Points Web page series at The University of Texas Health Science Center at San Antonio (UT HSC) Libraries is to provide specialized information resources in an organized online format. Highlighted resources include databases, journals, UT HSC campus information, funding sources, PubMed® RSS article feeds, and information about professional associations. This paper discusses the development process, planning, challenges, and outcomes of the Starting Points series.  相似文献   

Sharing MedlinePlus®/MEDLINE® for Information Literacy Education (SMILE): A Dental Public Health Information Project     

Julie K. Gaines  Linda S. Levy  Keith W. Cogdill 《Medical reference services quarterly》2013,32(4):357-364

The SMILE project represented a partnership among the University of Texas Health Science Center at San Antonio Libraries, the Gateway Clinic in Laredo, and the San Antonio Metropolitan Health District. The project focused on improving dental practitioners' access to reliable information resources and integrating the best evidence into public health dental practice. Through its training program, SMILE cultivated a set of “power information users” among the dentists, dental hygienists, and community health workers (promotores) who provided public health preventive care and oral health education. The dental public health practitioners gained information literacy skills and increased their knowledge about reliable sites such as blogs, PubMed®, and MedlinePlus®. This project fostered opportunities for expanded partnerships with public health personnel.  相似文献   

Endurance of Undergraduate Attitudes Toward Older Adults     

Brooke Funderburk  JoAnn Damron-Rodriguez  Lené Levy Storms  David H. Solomon 《Educational gerontology》2013,39(6):447-462

This cross-sectional study assessed undergraduate attitudes toward older adults and attitude endurance 3 to 18 months after aging coursework. Survey respondents included 349 students who took an aging elective and 430 comparison students. Aging-elective students indicated more positive attitudes than comparison students. Attitudes did not vary across 3 groups staggered by time elapsed from completing the course until testing (3 to 18 months). 4 variables accounted for the variance in attitudes toward elders at a statistically significant level: majoring in biology, having frequent or occasional contact with unrelated older adults, taking an aging course, and post-course knowledge of aging.  相似文献   

Digital Module 11: Bayesian Psychometric Modeling https://ncme.elevate.commpartners.com     

Roy Levy 《Educational Measurement》2020,39(1):94-95

In this digital ITEMS module, Dr. Roy Levy describes Bayesian approaches to psychometric modeling. He discusses how Bayesian inference is a mechanism for reasoning in a probability-modeling framework and is well-suited to core problems in educational measurement: reasoning from student performances on an assessment to make inferences about their capabilities more broadly conceived, as well as fitting models to characterize the psychometric properties of tasks. The approach is first developed in the context of estimating a mean and variance of a normal distribution before turning to the context of unidimensional item response theory (IRT) models for dichotomously scored data. Dr. Levy illustrates the process of fitting Bayesian models using the JAGS software facilitated through the R statistical environment. The module is designed to be relevant for students, researchers, and data scientists in various disciplines such as education, psychology, sociology, political science, business, health, and other social sciences. It contains audio-narrated slides, diagnostic quiz questions, and data-based activities with video solutions as well as curated resources and a glossary.  相似文献

The Onion and the geopolitics of satire     

Edward C. Holland  Adam Levy 《Popular Communication》2018,16(3):182-195

This article considers the representation of global events in The Onion, a satirical news publication. Drawing on a content analysis of headlines and news stories, the article offers a set of general conclusions about the publication’s geographical and topical focuses. When considered in aggregate, the headlines offer an implicit critique of the mainstream media and coverage of international events. The idea that The Onion is a critical voice is, however, subject to interrogation. The Onion should be recognized with other satirical outputs as a profit-oriented enterprise, with appeal to key demographics and growing connections to multinational corporations. Yet The Onion’s position is further complexified through its direct engagement with international actors who do not get the joke.  相似文献

Criminal Justice Professionals’ Knowledge of Institutional Review Boards (IRBs) and Compliance with IRB Protocol     

Christine Tartaro  Marissa P. Levy 《Journal of Criminal Justice Education》2013,24(3):321-341

Institutional Review Boards (IRBs) perform an essential function in the protection of human participants. A survey was conducted on Academy of Criminal Justice Sciences members to determine their perceptions of IRBs as well as their knowledge of IRB principles and the extent to which they follow IRB protocol. Size of the researcher’s institution, number of research articles, number of years in active research, and number of external grants were also studied in relation to knowledge of IRB guidelines and number of IRB protocol infractions. Findings include significant correlations between involvement in research and engaging in research activities that are against IRB rules.  相似文献
